The Best-Selling Introduction to Digital Communications: Thoroughly Revised and Updated for OFDM, MIMO, LTE, and More.

With remarkable clarity, Drs. Bernard Sklar and fred harris introduce every digital communication technology at the heart of today’s wireless and Internet revolutions, with completely new chapters on synchronization, OFDM, and MIMO.

Building on the field’s classic, best-selling introduction, the authors provide a unified structure and context for helping students and professional engineers understand each technology, without sacrificing mathematical precision. They illuminate the big picture and details of modulation, coding, and signal processing, tracing signals and processing steps from information source through sink. Throughout, readers will find numeric examples, step-by-step implementation guidance, and diagrams that place key concepts in clear context.

This third edition is intended to provide comprehensive coverage of digital communication systems for senior-level undergraduates, first-year graduate students, and practicing engineers. Although the emphasis is on digital communications, necessary analog fundamentals are included because analog waveforms are used for the radio transmission of digital signals. The key feature of a digital communication system is that it deals with a finite set of discrete messages, in contrast to an analog communication system, in which messages are defined on a continuum. The objective at the receiver of a digital system is not to reproduce a waveform with precision; it is instead to determine from a noise-perturbed signal which of the finite set of waveforms had been sent by the transmitter. In fulfillment of this objective, there has arisen an impressive assortment of signal processing techniques.
