Wireless communications, advanced radar and sonar systems, and security systems for Internet transactions are contemporary examples of systems that employ digital signals to transmit information. This volume affords comprehensive, up-to-date treatment of the methodologies and application areas throughout the range of digital communication where individual signals, and sets of signals, with favorable correlation properties play a central role. Some application areas covered include Code Division Multiple Access (CDMA) signals such as those in use for cell-phone communication; digital systems for coded radar and sonar signals; and methods for secure authentication and stream cipher cryptology. The authors provide the necessary mathematical background to explain how the signals are generated and to show how the signals satisfy the appropriate correlation constraints.
The decision about how to send a signal through the atmosphere is a complex decision which must include: getting an intelligible signal through the transmission system in spite of transmission noise, atmospheric effects, equipment noise; increasing the information throughput by data compression; providing differing levels of security depending on the nature of the data; and many other problems.This book is a fairly rigorous mathematical analysis of the methodoligies and application areas throughout the range of digital communications. Important applications addressed in the book include Code Division Multiple Access (CDMA) already used in cell-phones; radar and sonar signals; and others.This book is intended for use as a reference work for engineers and computer scientists as well as to serve as a textbook for a course in digital communications.The book gives a URL for a web site to be used for additions, corrections, and updating. Unfortunately the URL in the book is wrong, the correct URL is [...] As of the time of this review, there are no additions or updating, and a couple of minor corrections.
