Digital Communications: Fundamentals and Applications (2nd Edition) [Repost]

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.
