Applications = Code + Markup: A Guide to the Microsoft Windows Presentation Foundation (Pro

Book Description

In this book, Windows programming legend Charles Petzold covers in parallel the two interfaces that make up the Windows Presentation Foundation (WPF). From the outset, the reader can shift focus seamlessly between Extensible Application Markup Language (XAML) and C# to see them as flip sides of the same processes. Beginning in the first chapter, Petzold presents the general syntax of the XAML and corresponding programming code with numerous illuminating examples on how the two correspond and interrelate. The book builds on this base, providing the classic Petzold Windows user interface (UI) treatment, to show Windows developers how to create next-generation interfaces for their applications.

very disappointing.......2007-07-20

I've been a Windows developer for around 10 years or so and have read dozens of developer books. This is only the second one I can remember returning.

I had previously read Programming Windows Presentation Foundation (Programming) (which I recommend) but was looking for more. At 900+ pages, and with the good reviews and experience of the author, this book looked like a good choice. Unfortunately, after the first 450 pages, I decided that my time would be much better spent simply rereading the the Chris Sells book instead.

The main problem is the style in which the book is written. It could easily be edited down to half its size. How many times do I need to read "Button btn = New Button()" in a code example? I know some people prefer fully functional examples over code snippets but after a while it really got ridiculous. The code examples eventually became almost useless to read because it became so much work to sort out the irrelevant and insignificant details. On top of which 90% of the code samples are examples of THE WRONG WAY to do a UI in WPF (i.e. in C# instead of XAML). I understand the second half of the book is all XAML, but spending 450+ pages on techniques you would NEVER ACTUALLY USE is a waste of my time.

A lot of bloat also came from a lack of focus on who the book is written for: experienced .NET/C# developers. I don't need to have "using" statements explained to me, I know how .NET dialogs work, etc... From the "Printing" chapter: "The Print dialog also includes a Number of Copies field. Enter a number greater than 1 in this field and the PrintVisual method prints multiple copies." Really. I never would have figured that out on my own.

There is a lot of good information here but it is simply not worth the time it takes to extract it from "Button btn = new Button()" statements. Maybe this book is a demonstration that you're never to old for an editor. I'm going back to O'Reilly books.

I appreciate this book so much.......2007-06-14

I think that Petzold was reading my mind when he wrote this book. I don't like XML, and I don't like "cheating" with XAML when you can write good clean C#. The first half of this book is entirely C# programming in WPF. I am using this book to help me write an abstraction layer above WPF. That simply would not be possible with XAML, which in my opinion places the design of the application at too low of a level. Petzold leaves no stone unturned, and whenever something seems weird, he doesn't ask us to trust him that it makes sense; he explores it in depth for us. I can't imagine that many other authors go through that kind of trouble when they're writing on tight deadlines. Petzold tells it how it is, and he includes the "why." Therefore, I recommend this book to anyone who strives to become a bit of an expert in WPF, not just a get-the-job-done programmer. I would consider this an advanced book at times because I find myself reading and re-reading sections to understand it. The explanation is there, but it's not trivial, and with so many pages in the book already, there is no room to be wordy.

WPF and XAML explained........2007-05-29

Written by a professional for the professional! This book reminds one on how things aught to be done in C# and gives an insight of WPF and its mechanics. A must have book for the serious developer and even the amature will benefit from Charles Petzold insight.

The Other Side of WPF.......2007-05-20

I purchased this book late last year, took a vacation and spent a week reading it cover to cover. Since that time I've written several production WPF applications of moderate complexity that are several generations beyond the WinForms and WebForms apps I had been writting. Several months ago, when it was released, I also got to read Adam Nathan's book on the topic of WPF. Having read both books and used WPF to produce better apps under the usual deadlines, I can honestly say that I benefited from the additional insights gleaned from both books.

When I read Petzold's book and saw the code first approach with XAML introduced later, my impression was this seemed contrary to the preference to XAML I saw espoused in other sources and beta books. As I reconciled this new technology being taught by a long tenured veteran, I got a feeling that perhaps earlier concepts around Win32 UI programming may be the lens through which the author is presenting the material on how to best apply WPF. Needless to say, I paid attention and got more value than I anticipated and beyond what I learned from his WinForms book of similar size. While Adam Nathan's book was a more efficient read for me, and one that I could appreciate in its attention and orientation to the more mainstream presentation of WPF, I think that later book in conjunction with this one is quite useful.

My real critique of Petzold's book was that it should have played more to the what may have been the author's strengths in elucidating the API and imperative coding in WPF. Such an approach may have been a great book as a complement to the many XAML focused ones to follow. I believe the API focused chapters that do exist makes Petzold's book a great contribution to WPF knowledge and application. Sure, in my day-to-day I strictly enforce the UI separation by defining a majority of UI elements in XAML. Without Petzold's book I probably would have went further in this approach. Yet, in reading his material I was reminded of and given an appreciaton for the techniques and the potential benefits of using the WPF API more explicitly to peform a range of tasks that works in concert with XAML declared elements to provide the complete solution.

For understanding the benefits and mechanisms of the WPF API this is a great complement for the many XAML dominated books out there. I rate it a 5 because I learned a greater variety of interesting details related to the WPF API than I would have been predisposed to explore or unable to find just using the MSDN documentation. For WPF API knowledge and understanding that can enhance the code side of solutions defined to a greater or lesser degree in XAML this is a great buy.

Nice cover, bad content.......2007-05-09

The writer is a guru in the field of Winforms applications.
The first part of the book is rather from this angle, the Second part discusses the markup (XAML). The book contains much code (C#), enumerations and is as a result, badly readable.
It contains no information about the technique behind the WPF, essential for understanding the new generation of applications which you can make.

If you want to learn the WPF I reccommend the book "Windows Presentation foundation Unleashed" of Adam Nathan. That one is filled with colours impressions and examples, very usefull working with markup.

Amazing book.......2007-07-13

I have the first version of this book. Now I am so glad to have the second version too. It has great improvement. It added quite lot of recent FEC tech in, including Turbo coding, LDPC coding. Besides, it is quite easy for a engineer to understand, not awkward as some math equation filled textbooks. Its block diagram can be easily understood by an engineer like me. Amazing book!

Both clear and complete.......2007-05-15

Not only does this book contain almost all the important information about coding you could hope for, but it's written in such a clear way with such a consistent notation that it's also wonderful for learning. This book is more than twice as long as the first edition and serves as a great graduate-level text or reference for someone designing ECC systems.

Foremost book in the field.......2004-10-19

I had the previous version of this book as my text at USC. This version is a huge improvement over the last one. This one covers all the new advances and adds emphasis on the use of coding to communications channels. A complaint I had of the last version was that it under-emphasized coding gains and Eb/N0 vs. BER performance figures. This book has overcome many of those difficulties. It is still a bit ponderous in places but then it is the only book that covers the material in this much detail, truly a Bible of the field. It is a great graduate level text and a must-have book for any comm engineer. Charan Langton complextoreal.com

very useful for both beginners and experts.......1999-06-12

a very detailed book for getting into Galois field arithmetics, cyclic codes, convolutional codes, ... As a very beginner I had no big problems understanding the content. I am not the type of guy who could understand just by reading the theory - this book gives a lot of very useful examples, so you could call it fun reading it!

Excellent applications-based approach to Error Correction.......1998-10-05

Lin and Costello produced an excellent text which is targeted towards engineers as opposed to mathematicians. The mathematics behind error correction can be extremely intensive and, with other texts, I quickly become lost in complex proofs. Lin and Costello present error correction in method, with plenty of good examples, which those who need to know how to apply it can understand and the gory details of the theory are not as important. I used this book as my introduction to error correction and it continues to be a great reference book. The only drawback in it is since it was published in '82, it stops at convolutional coding and does not cover trellis-coded modulation or turbo codes.

Khalid Sayood's textbook-style Introduction to Data Compression is the definitive guide to all kinds of compression schemes. Early chapters establish the mathematics involved in basic compression techniques, including lossless and lossy compression as well as the fundamentals of information theory that lay the groundwork for common forms of compression. (The book contains all the relevant formulas, although those who don't need such mathematical detail will still be able to understand the book.)

A good portion of the book examines various compression schemes, their strengths and weaknesses, and what content they work best for. Introduction to Data Compression begins with lossless compression schemes, which lose no information during the compression/decompression process. Huffman Coding, a well-established compression scheme, and arithmetic and dictionary coding also receive excellent treatment. In addition, the author takes on lossless compression for images.

For lossy compression, Sayood discusses schemes that use quantization, where a range of values is compressed in some way. He also describes scalar, vector, and differential encoding and fractal compression. A final chapter looks at video encryption (which often combines techniques from earlier chapters). Many of the compression schemes include examples from image and sound files, but the book considers a wide variety of video schemes too. This rich and confidently written text collates a lot of research and can serve as both textbook and source for designers who need a readable and mathematically solid introduction to data compression.

Book Description

The second edition of Introduction to Data Compression builds on the features that made the first the logical choice-for practitioners who need a comprehensive guide to compression for all types of multimedia and instructors who want to equip their students with solid foundations in these increasingly important and diverse techniques.
This book provides an extensive introduction to the theory underlying today's compression techniques, with detailed, instruction for their application. All of the coverage has been updated to reflect the state of the art in data compression, including both new algorithms and older methods for which new uses are being found. And the downloadable software gives you the opportunity to see firsthand how various algorithms work, to choose and implement appropriate techniques in your own applications, and to build your own algorithms.

* Fully updated to cover the most recent lossy and lossless compression techniques, including wavelets, subband coding, predictive lossless techniques, and Huffman coding variants.
* Explains established and emerging standards in depth: JPEG 2000, JPEG-LS, MPEG 2, Group 3 and 4 Faxes, JBIG 2, ADPCM, LPC, CELP, and MELP.
* Includes an new chapter providing the mathematical background required for understanding wavelets and subband coding.
* Via the companion Web site, provides source code that enables you to experiment with a wide range of compression techniques, along with sample data and updates on the latest developments in the compression field.

Accessible textbook on compression does not sacrifice rigor .......2007-05-19

This is one of those books that only gets a new edition when the author has something genuinely new to say, and this third edition of Sayood's excellent introduction to data compression is no exception. This particular edition is different from the second mainly in that there is a new chapter on audio compression that includes a description of the mp3 algorithm. Also there is additional information on the new video coding standards as well as the new facsimile standards.

As to the target audience for this book, if you are tasked with designing hardware or software implementations of data compression algorithms and you have some background in either electrical engineering or computer science, then this is a good book from which to learn and then to practice what you learn via some very good exercises. Some prior knowledge of information theory and random processes wouldn't hurt either. There is also an abundance of examples that are sprinkled throughout the book to illustrate concepts as they are presented. The author's approach in each chapter is to explain each concept in as an accessible manor as possible, present relevant equations, and then work an example using what has just been presented.

The book presents the mathematical preliminaries in chapter 2, and chapters 3 and 4 are dedicated to coding algorithms which include Huffman coding, arithmetic coding, Golumb-Rice codes, and Tunstall codes. Chapters 5 and 6 describe many of the popular lossless compression methods and their applications. These methods include LZW, BWT, and DMC. Chapter 7 describes various lossless image compression algorithms such as JBIG as well as their applications. Chapter 8 discusses the mathematical background of lossy compression standards. Chapters 9 and 10 concentrate on quantization since it is the basis of most lossy compression schemes. Chapter 11 discusses differential encoding techniques such as DPCM and delta modulation. Included is a discussion of the CCITT G.726 standard.

Chapter 12 is the third and final chapter dedicated to mathematical foundations. It is meant to prepare the reader for the chapters on transform, subband, and wavelet based methods that encompass the following three chapters. The JPEG standard is covered in chapter 13, the CCITT G.722 standard in chapter 14, and the EZW, SPIHT, and JPEG2000 standards are covered in chapter 15. Chapter 16 focuses on audio compression and includes descriptions of the various MPEG audio compression schemes including mp3. Chapter 17 switches gears somewhat and covers techniques in which the data to be compressed is analyzed and a model is produced. This model is then used to synthesize the data and is quite useful in speech compression. Chapter 18 deals with video compression and diverges from the book's central theme of dealing with techniques rather than applications. The chapter discusses the H.261 standard as well as MPEG-1, MPEG-2, and MPEG-4 standards.

The website for the book, found at the publisher's site, contains a large number of C programs dealing with compression. I haven't tried to use any of these yet, so I can't speak to their validity.

A great textbook.......2006-02-11

This book has all the ingredients for a great textbook. It provides good theoratical background without going into unnecessary details, gives lot of discussion about applications, provides great exercise problems, and above all it has outstanding examples that makes some of the difficult concepts easy to understand.

Data compression needs a lot of background in information theory and other areas specific to speech, image processing etc. It is impossible to give a rigourous theoratical treatment of all of those in one volume. A strong point of this book is that it gives you just enough background on a variety of topics - without making the whole book obscure. In that respect, it is very application and implementation oriented. It is in fact what it says it is: A very good "INTRODUCTION to Data Compression"

Very good coverage.......2004-12-27

The best thing about this book is the coverage and organization of the material. Sayood covers a wide variety of compression topics without getting into the nitty gritty details of them all. Thats why its an "Introductory" book. This book is a valuable resource for those who want to know the basics of various compression techniques and can be used as a starting point for further details. Some topics like arithmetic coding are covered in more detail than others. The book is also organized nicely with mathematical foundations provided as and when necessary.

"The" Definitive Guide.......2004-02-16

Amazon claims that this is "the definitive guide". I have to agree with them because this book is the only broad grey pages introduction to data compression that I have been able to find, and it is very well written.

If you are only casually interested in data compression this book is not for you.

If you are interested in adding compression to your application and your data falls into a common category, sound, video, text ect this book is probably not for you. You should look to the open source community or buy an off the shelf product.

But if your data is odd or unique like say telemtry data (I'm sure there are other examples I just can't think of any) and you need to design a compression scheme for your data this book is "the only" book for you.

If you want to begin research into data compression and you are a newbie this book is a must have.

Very well-written book, software not so good.......2003-04-25

The book is one of the clearest I have read as a text book. Why cant everybody write like this?? There is very good flow throughout the text.

Very good intro textbook. It gives short, detailed preps to various coding areas (linear, cyclic, convolutional). The biggest advantage this book has is that it does not throw at You tonnes of unnecessary info (like many other thick books do). That is, it assumes reader has some basic understanding of algebra and probability theory. Let's say, it gives good theoretical presentation such that the reader gets good theoretical understanding, it is not example-based.

Douglas R. Stinson's Cryptography: Theory and Practice is a mathematically intensive examination of cryptography, including ciphers, the Data Encryption Standard (DES), public key cryptography, one-way hash functions, and digital signatures. Stinson's explication of "zero-sum proofs"--a process by which one person lets another person know that he or she has a password without actually revealing any information--is especially good.

If you are new to the math behind cryptography but want to tackle it, the author covers all of the required background to understand the real mathematics here. Cryptography includes extensive exercises with each chapter and makes an ideal introduction for any math-literate person willing to get acquainted with this material.

Book Description

Cryptography is an outstanding book that covers all the major areas of cryptography in a readable, mathematically precise form. Several chapters deal with especially active areas of research and give the reader a quick introduction and overview of the basic results in the area. Cryptography provides the mathematical theory that is necessary in order to understand how the various systems work. Most algorithms are presented in the form of pseudocode, together with examples and informal discussion of the underlying ideas. The book gives careful and comprehensive treatment of all the essential core areas of cryptography. Also, several chapters present recent topics that have not received thorough treatment in previous textbooks. Such topics include authentication codes, secret sharing schemes, identification schemes, and key distribution.

Customer Reviews:

It lacks theory.......2007-06-15

The book is good about protocols and methods but it lacks the real theory underlying modern cryptography.
For a more serious treatment of these topics i recommend "Introduction to modern cryptography" by J. Katz and Y. Lindell (which i read in form of draft) and "Foundations of Cryptography Vol. 1" by O. Goldreich.

A good reference.......2007-04-24

I may not intend to read this book from cover to cover but would rather use it as a reference. As an engineer I like chapter 2 Shannon's Theory which gives an answer to why a cryptosytem is secure.

Personally I am doing the job related to network security and perfer to recommend the book by C. Kaufman, R. Perlman, and M. Speciner:Network Security: Private Communication in a Public World, Second Edition.

Good book after Schneier's Non-Mathematical Treatment.......2005-05-28

If you are an engineer trying to learn crypto, maybe get a book on number theory to go with this book. It'd be nice if there were fewer errors and more worked out problems, as well.

Overall a good effort but written by a mathematican so you need a book like Schenier's that explains how to use the tools. Maybe Scheier is the one I'd read first. Then read Stinson's to understand how the tools work because Scheier's book is mathematically barren.

Volume III of the Definitive Work.......2005-04-17

This book takes a fairly rigorous mathematical approach to cryptography. It is intended for upper level undergraduate and graduate students in mathematics, computer science and engineering. I suspect only the quite mathematically inclined computer science and engineering students will find this book helpful. This is not a Boy Scout how to do secret messages book, but a book that will give the professional the data needed to implement cryptographic software, and the mathematician hints on both code breaking and creating.

This is the third edition of this book. With the second edition, the author got rid of several several subjects that were not right at the core of cryptography, with the intend of doing a second volume. Instead, the art and scienct of cryptography has changed so fast during the past few years that a two volume approach isn't practical. Instead, he has produced this third edition that picks back up many of the subjects from the first edition. All of the material in this edition has been extensively re-written to incorporate the latest theories and practices.

In recent years the use of cryptography has increased by several orders of magnitude. Every time we buy something with a credit card, use on line banking, send a password to access e-mail, we use cryptography. With this growth, the interest at software companies, universities, and other places has grown accordingly and this text has become the standard by which others are compared.

Highly recommended for the serious student.

Could be a great book .... but it falls short.......2004-05-02

As other people have pointed out, this is not a mathematics book, and it is not an algorithm (recipies) book. It could be a great book for people that are interested in learning these tools to actually use them, either in a research or product development context (something besides homework). Unfortunately, the number of typos, in key mathematical expressions AND PORTIONS OF THE EXPLANATIONS is staggering. Go to the author's web page and you will find that some chapters, like 4 for example, average more than one typo per page (and some of these 'typos' are full sentences, or math expressions that do not look like anything that is actually printed on the page). If you do not have that errata sheet handy, you will waste a lot of time trying to understand the text, or trying to solve the exercises. If you are trying to learn from this book, without attending a class and without the errata, you will simply give up. It is a real shame because it has all the makings of a great book.

An undiscovered gem of compression algorithm details.......2006-04-08

This book covers a needed middle ground between the more formal books on the subject such as Sayood's "Introduction To Data Compression" and easy programmer-oriented books such as Nelson's "The Data Compression Book". This book is an encyclopedia of compression methods that briefly describes the technique of each method, along with any required math, and then shows the algorithm. Code is not shown in the sense that there are no CompressionAlgorithm.cpp files included that you can lift without knowing what you are doing. However, the algorithm pseudocode is such that you should be able to translate any algorithm into code without much trouble. I know that this book has helped me. I would suggest that any true student of data compression methods use this book in conjunction with Sayood's book. Use Sayood to get the mathematical background that you need. Then use this book to read the details of a particular algorithm in plain language. This book is truly an undiscovered gem for most in the field and I highly recommend it.

Very Complete - No Useless Filler.......2005-05-04

This is by far the most all-encompassing and thorough data compression book I have ever come across. Every method covered is carefully explained in great detail leaving no doubt as to how to implement it into your various projects. This is not just some ho-hum discussion of existing software and how to copy the coding of it, as some other texts turn out to be. For once, an author did not clutter his pages of pure compression information with mountains of proprietary source code or over abundant mathematical nonsense. This book is the real deal for true data compression enthusiasts looking to follow along in real world usages and research new methods. If your sole purpose is to draw up a statistical analysis of a particular algorithm, grab your calculator and go someplace else to write your term paper. To copy someone else's source code, search the net. For those of you interested in getting in there and really tackling modern compression methodology and adapting it to whatever your needs and desires may be, this is the only book you will ever need.

Many algorithms included, but no in-depth discussion.......1999-05-02

This book explains lots of algorithms, the author tries to give you a brief overview on each of them.

However, if you're interested in the concrete ideas and proofs on how the algorithms help you to compress your data, with some mathematical works, the book isn't enough. You'll find it difficult if you want to implement the algorithms by merely reading the book.

Some idea are not clearly explained too, say, the the information on Gzip is just a summary of the GNU documentation with no in-depth discussion.

Anyway, this book is a great one judging from the (sad) fact that there are not many references on the subject.

A comprehensible but not very profound book.......1998-12-13

The book is quite comprehensible also if English is not your mother tongue.

Many algorithms are touched on, but often not profound enough to allow programers to implement the methods. Also the subtitle "The Complete Reference" is questionable: I bought the book because I was looking for facts about the Elias-Willems algorithm. In vain!

Decent overview of many algorithms.......1998-10-24

This book is more about breadth than depth. It explains the workings of pretty much every data and image compression algorithm you've ever heard of. It's not as strong on theory as Bell/Cleary/Witten's _Text Compression_, and doesn't have source code like Nelson's _The Data Compression Book_, but it does a fine job of filling in the space between.

Book Description

This is an introduction to the mathematics involved in the intriguing field of cryptology, the science of writing and reading secret messages which are designed to be read only by their intended recipients. It is written at an elementary level, suitable for beginning undergraduates, with careful explanations of all the concepts used. The basic branches of mathematics required, including number theory, abstract algebra and probability, are used to show how to encipher and decipher messages, and why this works, giving a practical as well as theoretical basis to the subject. Challenging computer programming exercises are also included. The book is written in an engaging style which will appeal to all, and also includes historical background on some of the founders of the subject. It will be of interest both to students wishing to learn cryptology per se, and also to those searching for practical applications of seemingly abstract mathematics.

well done.......2003-02-23

As I do not work for M.I.6, the N.S.A. or some other `Secret Service' a computer program as Wolfram's ` Mathematical Explorer' [at Amazon for $75, or so] which can encrypt a message by R.S.A [heavy duty crypto] is `really' all I need.

I have a number of books on all kinds of cryptography ... `classical' crypto, `Codes' [different from cyphers], number theory and so on.

While there are `better' books on specific parts of cryptology this book is by far the best overall introduction.

The title of this book scared me a bit. I have never been that `comfortable' with some sorts of maths and this book `sounded' brutal, and while it is a `math' book it is really not impossible to `figure out' [although some spots I must have read twenty times but thats the topic].

`REQUIRED BACKGROUND'

You can `do' with less but it helps to know basic algebra and understand variables. The vocabulary and nomenclature of areas as Set Theory and Probability [which I had to `study up' on] would be `nice' but you can `slide' without them,

Reading level: age 14 through senility :-) [ but a challenge for those `dead and encrypted'.
`Classical', pen and paper, cryptology: B+
Clear Writing: A-
The `History' of cryptology: C+
Physical [binding and paper, type, type size ... ] B

Also covered in detail is "public key' cryptography which as I wrote I do by `pre - written' computer program.

Wonderful book.......2002-03-06

I *loved* this book.

It covers the essential number theory required to understand various encryption schemes, and while it is a thin book, it doesn't omit any steps between various mathematical steps (" ... and then magic happens ..."). You end up with the satisfying feeling of being able to derive the proof for RSA, starting from high-school math.

Highly recommended.

Some math is just plain fun and this is one such area.......2001-04-11

I cannot speak for the female side of the human race, but when I was young all the boys wanted to be a spy. We formed clubs and pretended to be secret agents. It was such great fun to create and use the codes to encrypt, pass and decode our important messages. Reading this book took me back to those days, not only reminding me of the good times we had but also how serious encryption is.
This book was a good deal of fun to read, but underlying the fun there is an air of extreme seriousness. It is not an exaggeration to say that secure encryption is the key to the efficient functioning of the global economy. Billions of dollars are electronically moved every day and without the security of unbreakable encryption, it would all be too unreliable to use. If the current codes were proven to be breakable, it would be a catastrophe, probably the only threat to the world economy that does not involve a major natural disaster.
The mathematics of encryption are surprisingly easy to understand. Starting with the simple substitution ciphers and moving through the more complex polyalphabetic and polygraphic substitutions, the techniques to create and break them are described. For most of the codes, the most complex mathematics needed to understand them is a basic understanding of matrices and how they are added and multiplied. It is only in the last chapter of public key cryptography where some advanced mathematics of number theory are used. Each chapter ends with a set of problems and solutions to the even ones are given in an appendix.
This would be an excellent textbook for a course in applied mathematics. There is an inherent fascinating quality to the subject matter and the tales of encryption are very well done. I strongly recommend that you read it.

Book Description

An unparalleled learning tool and guide to error correction coding

Error correction coding techniques allow the detection and correction of errors occurring during the transmission of data in digital communication systems. These techniques are nearly universally employed in modern communication systems, and are thus an important component of the modern information economy.

Error Correction Coding: Mathematical Methods and Algorithms provides a comprehensive introduction to both the theoretical and practical aspects of error correction coding, with a presentation suitable for a wide variety of audiences, including graduate students in electrical engineering, mathematics, or computer science. The pedagogy is arranged so that the mathematical concepts are presented incrementally, followed immediately by applications to coding. A large number of exercises expand and deepen students' understanding. A unique feature of the book is a set of programming laboratories, supplemented with over 250 programs and functions on an associated Web site, which provides hands-on experience and a better understanding of the material. These laboratories lead students through the implementation and evaluation of Hamming codes, CRC codes, BCH and R-S codes, convolutional codes, turbo codes, and LDPC codes.

This text offers both "classical" coding theory-such as Hamming, BCH, Reed-Solomon, Reed-Muller, and convolutional codes-as well as modern codes and decoding methods, including turbo codes, LDPC codes, repeat-accumulate codes, space time codes, factor graphs, soft-decision decoding, Guruswami-Sudan decoding, EXIT charts, and iterative decoding. Theoretical complements on performance and bounds are presented. Coding is also put into its communications and information theoretic context and connections are drawn to public key cryptosystems.

Ideal as a classroom resource and a professional reference, this thorough guide will benefit electrical and computer engineers, mathematicians, students, researchers, and scientists.

An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.

A great book by a great teacher.......2007-09-11

I took the class the Dr. Moon and I spent some time proof-reading it. I have read other texts on this material and some of them are quite hard to understand. Usually it is because there are too few examples.

In this book there are many examples to follow. There are problems that will test your theoretical and your practical knowledge of the subject. If you need an in-depth get-you-there book on this subject complete with programming examples, this is the book for you!

A very well written Introduction to Coding Theory.......2007-01-24

Error Correction Coding is very well written and easy to follow. Explanations are concise, and the book is filled with examples as well as coding assignments that really drive the principles home.

Book Description

Although devoted to constructions of good codes for error control, secrecy or data compression, the emphasis is on the first direction. Introduces a number of important classes of error-detecting and error-correcting codes as well as their decoding methods. Background material on modern algebra is presented where required. The role of error-correcting codes in modern cryptography is treated as are data compression and other topics related to information theory. The definition-theorem proof style used in mathematics texts is employed through the book but formalism is avoided wherever possible.
