Book description
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 todays wireless and Internet revolutions, with completely new chapters on synchronization, OFDM, and MIMO.
Building on the fields 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.
Understand signals, spectra, modulation, demodulation, detection, communication links, system link budgets, synchronization, fading, and other key concepts
Apply channel coding techniques, including advanced turbo coding and LDPC
Explore multiplexing, multiple access, and spread spectrum concepts and techniques
Learn about source coding: amplitude quantizing, differential PCM, and adaptive prediction
Discover the essentials and applications of synchronization, OFDM, and MIMO technology
More than ever, this is an ideal resource for practicing electrical engineers and students who want a practical, accessible introduction to modern digital communications.
This Third Edition includes online access to additional examples and material on the books website.
