Here's an authoritative, cutting-edge resource that gives you a thorough understanding of CDMA transmission and detection. It offers practical guidance in designing interference-reducing multi-user receivers for mobile radio systems and multi-user adaptive modems for accessing satellite earth stations. The book provides in-depth descriptions of CDMA principles, and of linear and non-linear multi-user detection, and covers the fine details of the realization of a linear multi-user receiver. Extensively supported with over 300 equations and more than 95 illustrations, the book enables you to devise accurate system models of both a cellular TD-CDMA radio interface and an asynchronous satellite radio interface. It allows you to choose among different architectural solutions for both linear multi-user receivers to be operated in TD-CDMA radio systems and adaptive linear CDMA receivers in satellite asynchronous CDMA systems.
