Résumé

The comprehensive, up-to-date guide to wideband digital wireless communication methods Edited by Andreas F. Molisch, with contributions from George Chrisikos, Savo Glisic, Alois M. J. Goiser, Brian Hart, Aarne Mammela, Thomas May, Andreas F. Molisch, Hermann Rohling, Desmond Taylor, Giorgio Vitetta, and Moe Z. Win. Wideband digital wireless systems are poised for enormous growth, driven by wireless Internet access and other compelling applications. In Wideband Wireless Digital Communications, Andreas F. Molisch has brought together the field's leading contributors in a timely, thorough guide to the state of the art. This book offers comprehensive technical explanations and comparisons of every leading wireless wideband approach used in today's systems, as well as those for the new third-generation systems such as UMTS, CDMA-2000, and HIPERLAN2, and features an extensive bibliography. Coverage includes:

Key data for the air interface of leading digital wireless systems, including GSM, IS-95, and IS-54
Unequalized systems: transmitter and receiver models, computation methods and performance of standard modulation methods, advanced modulation formats, adaptive sampling, and antenna diversity
Equalization: channel description methods, optimum decision rules (maximum likelihood sequence detection, maximum a-posteriori bit and symbol detectors, matched filter bound), and equalization algorithms (Viterbi algorithm, reduced-complexity MLSD, decision feedback equalizers, linear equalizers, diversity)
Orthogonal Frequency Division Multiple Access (OFDM): basic transmission/reception techniques; shaping of basic pulses; timing and carrier frequency synchronization; modulation/demodulation; coding; and peak-to-average reduction techniques
CDMA: design, standard and advanced Rake receiver structures, code acquisition/tracking, channel estimation, and capacity issues Next-generation wideband wireless systems present unprecedented challenges at every stage of the design process. With Wideband Wireless Digital Communications, engineers and other technical professionals have a single comprehensive resource for solving these problems-and delivering systems with optimal performance and capacity.
