Informationen zum Autor Diakoumis Gerakoulis is the author of CDMA: Access and Switching: For Terrestrial and Satellite Networks, published by Wiley. Evaggelos Geraniotis is the author of CDMA: Access and Switching: For Terrestrial and Satellite Networks, published by Wiley. Klappentext CDMA: Access and Switching addresses two unique uses of CDMA. The first is its use as a generalized method for multiple access communications and the second is its use in switching applications. Hence, the concepts introduced will enable readers to understand that multi-user communications (whether access or switching) can be presented as generalized code division networks. Each new application presented is assessed and evaluated while each innovative design is followed by rigorous performed analysis. * Introduces the concepts of generalized CDMA and code division switching and analyzes spreading sequences for orthogonal, quasi-orthogonal and pseudo-orthogonal access systems * Presents the Satelite Switched CDMA (SS/CDMA) as a system application and evaluates its end-to-end BER performance and throughput * Features methods and procedures for random access, synchronization and carrier demodulation in CDMA networks and examines the CDMA performance under non-linear amplification * Discusses methods of adaptive power control and multi-user detection in asynchronous CDMA networks Such a novel approach will be of great interest to researchers and will also benefit forward-looking system architects and designers. For graduate level students undergoing research work in terrestial wireless and satellite networks it will be a unique learning experience. Zusammenfassung CDMA is an integral part of next generation wireless communications. This work covers both CDMA and TDMA-based satellite communications. It provides an overview of related satellite systems and services and presents research and designs of spectrally efficient systems. Inhaltsverzeichnis Preface. The Generalized CDMA.
