Enhanced descriptions from Syndetics:
in order to develop products at the forefront of the wireless communications market, you must have an understanding of spread spectrum technology (known commercially as CDMA), the future technology of the cellular network. Written by a leader in the creation of CDMA, this book introduces you to the fundamentals of digital communications and spread spectrum technology. You will find detailed information on signal generation, synchronization, modulation, and error-correcting coding of direct-sequence spread spectrum signals. The book also shows you how these physical-layer functions relate to link and network properties involving cellular coverage, Erlang capacity, and network control.
Includes bibliographical references (p. 235-238) and index.
Introduction -- Random and pseudorandom signal generation -- Synchronization of pseudorandom signals -- Modulation and demodulation of spread spectrum signals in multipath and multiple access interference -- Coding and interleaving -- Capacity, coverage and control of spread spectrum multiple access networks.
