This book introduces key modulation and predistortion techniques for approaching power and spectrum-efficient transmission for wireless communication systems. The book presents a combination of theoretical principles, practical implementations, and actual tests. It focuses on power and spectrally efficient modulation and transmission techniques in the portable wireless communication systems, and introduces currently developed and designed RF transceivers in the latest wireless markets. Most materials, design examples, and design strategies used are based on the author’s two decades of work in the digital communication fields, especially in the areas of the digital modulations, demodulations, digital signal processing, and linearization of power amplifiers. The applications of these practical products and equipment cover the satellite communications on earth station systems, microwave communication systems, 2G GSM and 3G WCDMA mobile communication systems, and 802.11 WLAN systems.>

A propos de l’auteur
Wei Gao received a master’s degree and Ph.D. in electrical engineering from the Chinese Academy of Radio Technology in Beijing and University of California at Davis in 1987 and in 2001, respectively. He has more than two decades of industrial experiences in the field of wireless digital communications, mainly working at Xi’an Institute of Radio Technology, Harris Corp, VIA Technologies, and Broadcom Corp. His industrial experiences and research interests are in the areas of single channel per carrier (SCPC) FDMA system design for satellite earth station communications, high speed 128-QAM modem and adaptive algorithm designs for microwave communication systems, system designs and performance evaluations of RF transceivers, including RF predistortion algorithm design for PA linearization, for 2G GSM, 3G WCDMA, 802.11 WLAN, and 4G LTE standards. He has been a member of the IEEE since 1997.
