This internationally contributed handbook covers all aspects of signal processing as applied to digital communications, including adaptive coded modulation, channel modeling, estimation and identification, diversity combining and adaptive equalization, OFDM, cross-layer design, power control, neural networks, MCMC methods, and chaos. The editor puts a special focus on future 4-G mobile communication systems, including voice over IP, satellite mobile communications, and GPS receivers. Presented in a tutorial format, the reader will find a comprehensive survey of signal processing techniques used in mobile communications that concern the transmitter, the receiver, and the propagation channel.
