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.CD-ROM INCLUDED
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.--This text refers to the Hardcover edition.

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.
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.
