Description
This is your definitive reference on how networks transmit information. It covers the broad scope of physical-layer technologies, fundamental concepts, and techniques used in transmitting information over wire-line, optical, and wireless networks. The book provides a thorough understanding of such important topics as bandwidth, spectrum, noise, and channel capacity, and covers practical issues such as power budgets and bit-error rates. This authoritative resource helps you determine which communications protocol works best over which type of network, the tradeoff between transmission distance and data rate, and which scheme to use for modulation. By emphasizing systems and architectures, the book shows you how hardware, circuits, software, and techniques work together to transmit information. It covers information theory and explains how information is digitized, encoded, modulated, and multiplexed. Whether you are a seasoned professional or an engineering student, this book puts the knowledge you need to understand about information transmission systems right at your fingertips.
