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, Third 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, synchronization, 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:
-
Signals and spectra, including signal classification, spectral density, transmission, and bandwidth
-
Formatting, baseband modulation, and baseband demodulation/detection
-
Bandpass modulation and demodulation/detection
-
Communications link analysis and system link budgets
-
Channel coding: waveform, block, convolutional, and Reed-Solomon codes
-
Advanced turbo coding and Low-Density Parity Check (LDPC) techniques
-
Managing modulation and coding tradeoffs
-
Receiver and network synchronization
-
Multiplexing and multiple access
-
Spread spectrum overview and techniques
-
Source coding: amplitude quantizing, differential PCM, adaptive prediction, digital data, and more
-
Fading channels: challenges, characterization, and mitigations
-
The essentials of OFDM and MIMO technology
-
Long Term Evolution (LTE) Wireless, Software Defined Radio, 5G, and other advances
Dr. Bernard Sklar has over 50 years of experience in technical design and management positions at Republic Aviation, Hughes Aircraft, Litton Industries, and at The Aerospace Corporation, where he helped develop the MILSTAR satellite system. He is now President of Communications Engineering Services, a consulting company he founded in 1984. He has taught engineering courses at several universities, including UCLA and USC, and has trained professional engineers worldwide. Dr. Sklar has published and presented scores of technical papers, and is recipient of the 1984 Prize Paper Award from the IEEE Communications Society for his tutorial series on digital communications. He is a past chairman of the Los Angeles Council IEEE Education Committee.
Frederic J. Harris is professor of electrical engineering and CUBIC signal processing chair at San Diego State University (SDSU) and an internationally renowned expert on DSP and communication systems. The co-inventor of the Blackman-Harris Filter, his many technical papers include the seminal work "On the use of Windows for Harmonic Analysis with the Discrete Fourier Transform." The author of Multi-rate Signal Processing for Communication Systems, he received his B.S. from Brooklyn Polytechnic Institute, M.S. from SDSU, and PhD from Aalborg University, and did PhD course work at University of California, San Diego. An IEEE Fellow, he was co-editor-in-chief of Digital Signal Processing. In early 2010 the "Fred Harris Endowed Chair in Digital Signal Processing" fund was established by Eric Johnson and Qualcomm executive Peggy Johnson to help future students pursue careers in the communications specialty of electrical engineering, and to honor Harris's legacy.
