Product Description

From the Back Cover

  • The clear, easy-to-understand introduction to digital communications
  • Completely updated coverage of today's most critical technologies
  • Step-by-step implementation coverage
  • Trellis-coded modulation, fading channels, Reed-Solomon codes, encryption, and more
  • Exclusive coverage of maximizing performance with advanced "turbo codes"
"This is a remarkably comprehensive treatment of the field, covering in considerable detail modulation, coding (both source and channel), encryption, multiple access and spread spectrum. It can serve both as an excellent introduction for the graduate student with some background in probability theory or as a valuable reference for the practicing ommunication system engineer. For both communities, the treatment is clear and well presented."

– Andrew Viterbi, The Viterbi Group

Master every key digital communications technology, concept, and technique.

Digital Communications, Second Edition is a thoroughly revised and updated edition of the field's classic, best-selling introduction. With remarkable clarity, Dr. Bernard Sklar introduces every digital communication technology at the heart of today's wireless and Internet revolutions, providing a unified structure and context for understanding them -- all without sacrificing mathematical precision.

Sklar begins by introducing the fundamentals of signals, spectra, formatting, and baseband transmission. Next, he presents practical coverage of virtually every contemporary modulation, coding, and signal processing technique, with numeric examples and step-by-step implementation guidance. Coverage includes:

  • Signals and processing steps: from information source through transmitter, channel, receiver, and information sink
  • Key tradeoffs: signal-to-noise ratios, probability of error, and bandwidth expenditure
  • Trellis-coded modulation and Reed-Solomon codes: what's behind the math
  • Synchronization and spread spectrum solutions
  • Fading channels: causes, effects, and techniques for withstanding fading
  • The first complete how-to guide to turbo codes: squeezing maximum performance out of digital connections
  • Implementing encryption with PGP, the de facto industry standard

Whether you're building wireless systems, xDSL, fiber or coax-based services, satellite networks, or Internet infrastructure, Sklar presents the theory and the practical implementation details you need. With nearly 500 illustrations and 300 problems and exercises, there's never been a faster way to master advanced digital communications.


The CD-ROM contains a complete educational version of Elanix' SystemView DSP design software, as well as detailed notes for getting started, a comprehensive DSP tutorial, and over 50 additional communications exercises.

Format: Hardcover
A very well written book, of course covering all aspects of digital communications, but not ignoring analog parts of the chain (e.g. noise). Very clear explanations, useful examples, no BS. There are other books that might be equally interesting (Proakis,...), but you can be sure about this one.

By A Customer on 14 Mar. 2006
Format: Hardcover
I am a professional Electronics Engineer in the field of Digital Audio, and I was looking for introductory text on Digital Comms. Well, there's no denying that this book has plenty of content, but it reads terribly. If you try reading this book in a linear fashion, as I did with Chapter 1, you will find that the author darts back and forth through the example DCS in a seemingly random fashion. This spaghetti writing is further hampered by terrible grammar, punctuation and typographical errors. The theme continues throughout the book with huge blocks of text just copied and pasted from one chapter to another, there's just no decent structure to this text. The author appears to have simply compiled segments from other people's books and thrown it together. As a learning tool I don't recommend it, and as a reference book it would appear to be a little too dumbed down. I've sent mine back and ordered Haykin!

HASH(0x9b2d3620) out of 5 stars Digital Communications: Fundamentals & Applications, 2nd Ed. 26 Feb. 2001
By George Edwards - Published on Amazon.com
Format: Hardcover
This is one of the best books on the market for communications. As a university professor I am always looking for that special book that can take the student from the formative learning stage into maturity in the field of communication and signal processing. This book is an excellent text for such a journey. It provides a good mix of theory and practice with many worked examples. Unlike many texts in communications theory that provide their audiences with a lot of theory and abstractions that leave them confused, this book is so well written and the theory so well handled and presented, that its concepts are easily grasped. Then, to supplement this, the book has numerous worked examples showing practical applications. As an educator in the field of communications I have adapted this book for my course because its stated attributes above make my work in educating students that much easier. I recommend this book without reservation to anyone who needs a good reference in the field of communications.

HASH(0x9ae9a3e4) out of 5 stars Good overview but not mathematically rigorous 17 Sept. 2002
By Rajesh S. Raghavan - Published on Amazon.com
Format: Hardcover
Digital Communications by Sklar is an excellent introduction to the field for the student or the practicing engineer. There is a logical flow from beginning to end, and the book is written in an easy to read style, which allows the reader to grasp the engineering tradeoffs involved in digital communications.
The book is not mathematically rigorous; although formulas are presented, they are not derived. However, I feel that to correct this shortfall may make the book too long, and harder to read. I think it is better to get a general overview of the topic from this book, and to look to other sources where mathematical rigor is desired.
Some additional background is helpful, but not necessary to understand the mathematical details that are glossed over. These include a course in Detection and Estimation to understand concepts such as signal spaces, noise, decision regions and probability of error, and an introductory DSP course to understand the issues surrounding aliasing, quantizing, equalization, and source coding. Familiarity with Fourier Transforms and prior background with Probability and Random Processes is essential to understanding the math that is presented in the book.
Overall, I highly recommend this book for someone who wants to appreciate the engineeering constraints that need to be met in the design of digital communication systems.

HASH(0x9e974714) out of 5 stars A great book to learn comm. theory. 8 Mar. 2001
By miner49 - Published on Amazon.com
Format: Hardcover Verified Purchase
I was introduced to the 1st edition of this book as an undergrad at UCLA where Sklar taught. Since then as I have worked in the wireless and telecom fields, it has remained one of my main references. I've added other comm. books such as Proakis', but Sklar remains my favorite. It is well arrange, making it easy to reference any material you may be interested in. It touches on every area of comm. theory from modulation to coding. If you are looking for a general communication theory reference book, then this should be the one. But if you are only interested in learning in detail about one particular area of commmuncation theory such as CDMA or Trellis Coding, then you should seek a book specializing in that area only. No book can cover everything in the depth.

HASH(0x9e974db0) out of 5 stars A must for signal processing engineering 14 Jun. 2006
By Devin Cambridge - Published on Amazon.com
Format: Hardcover
Digital Communications: Fundamentals and Applications makes a fine addition to any signal processing engineer's library. Dr. Sklar manages to give a comprehensive view of the subject discussing Bandwidth Efficient Modulation, Bit Error Rates, Multiple Access signaling and a variety of other subjects. This book resides somewhere between upper division undergraduate and graduate level coursework. At this level, a certain amount of study is assumed, and this is an engineering textbook with derivations not listed for a variety of reasons (it is assumed that students are familiar with Fourier transforms and high level calculus. Information presented is for the purpose of Asic/FPGA/chip/software design with a lot of the formulas coming from industry definitions). The accompanying CD is fantastic and anyone looking to apply some of the knowledge with one of the best tools in the industry (Systemview) will find the CD invaluable.

HASH(0xa0c1c990) out of 5 stars Comprehensive, yet easy to understand digital comms text 23 Aug. 2001
By angyh@singnet.com.sg - Published on Amazon.com
Format: Hardcover
I have not read the first edition, but I have long depended on Sklar's tutorial articles in various publications to improve my understanding of digital comms concepts, so it was with some anticipation that I opened this book. It certainly did not disappoint; the author's characteristic style, which imparts an intuitive understanding rather than simply instruct, is present throughout. In certain sections, the theory is not just presented alone but supplemented with nuggets of practical knowledge.
Proakis is undoubtedly still the benchmark for such texts, but this book will be a valuable addition to the bookshelf for both students and engineers alike. Remember to have a look at the checklist in the preface to straighten out your concepts.
