More versatile, reliable, and robust than other signal processing techniques, spread spectrum CDMA systems are becoming widely accepted and promise to play a key role in the future of wireless communications. This comprehensive new book explains the main issues and makes the practical applications of spread spectrum CDMA available to network engineers and managers - and, with nearly 1,000 equations, the book provides you with the mathematical tools necessary to apply the technology to your network. In eight clearly written chapters, Spread Spectrum CDMA Systems for Wireless Communications outlines the main advantages of the spread spectrum technique, describes its key elements, and also...Presents important code acquisition strategies for direct sequence (DS) and frequency hopping (FH) systems - and the mathematics used for their analysis; Compares various code tracking loop systems, such as Delay Lock Loop (DLL) and Tau Dither Loop (TDL); Details receiver configurations based on CCD, SAW, and DSP matched filters; Examines system capacity issues related to the CDMA cellular network; Explains the CDMA overlay, packetized transmission in CDMA networks, and the problems of multiuser detection. You also strengthen your understanding of important topics such as automatic threshold detection, sequential and in lock/out of lock detectors, and discrete tracking loops for Slow Frequency Hopping (SFH). Chapter-end appendices provide insight into the newest CDMA standards, including the IS-95 standard. The practical design guidelines presented throughout the book make it a valuable reference tool for network designers, while updates on various performance aspects help mobile communications managers make better, more informed choices for their own systems. The book also serves as an excellent primer for post-graduate students in communications. Includes 166 illustrations.
