This is a 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. Throughout, Sklar helps students understand the big picture and delve into the details of current modulation, coding, and signal processing techniques. He traces signals and key processing steps from the information source through transmitter, channel, receiver, and information sink.
Digital Communications, 3rd Edition begins by introducing the fundamentals of signals, spectra, formatting, and baseband transmission. Next, Sklar presents practical coverage of trellis-coded modulation, Reed-Solomon codes, synchronisation, spread spectrum solutions, and much more. Throughout, he offers numeric examples, step-by-step implementation guidance, and block diagrams that place key concepts and techniques in clear context. Coverage includes:
