Summary:

Wireless Communications presents the most comprehensive coverage of this field which, in only a decade, has grown from a niche market into one of the most important industries. While previous systems were generally intended to provide mobile speech communications, mobile data communications have since developed.

This essential textbook on the principles and applications of mobile radio is an all-encompassing current treatment of the area, addressing both the traditional elements, such as Rayleigh fading, BER in flat fading channels, and equalization, and more recently emerging topics like multi-user detection in CDMA systems, OFDM and smart antennas. These fundamentals are related to practical systems, and the dominant wireless standards, including cellular, cordless and wireless LANs, are discussed.

Wireless Communications is an essential text for advanced undergraduate students with a working knowledge of standard digital communications, graduate students and practising engineers. It will also be an invaluable source of reference for wireless communications engineers.
