Focusing on recent discoveries in data rate limits and bandwidth, this is the first book to directly address the problems of wireless high data rates from a physical layer point of view. It details the author's new digital radio architecture, now emerging as a key technology for third generation wireless communications. This ground-breaking resource enables you to understand the interaction of theory and practice in multi-antenna technology and digital radio design, produce better modems for multi-antenna radio products, and relate traditional RF design parameters to modern communication systems design. It also provides analytical tools to evaluate end-to-end performance of the wireless link and new algorithms for wireless high data rate communications. Supported with over 440 equations and 120 illustrations, the work explains the fundamental theory for the transmission of digitally modulated signals with and without antenna arrays, and details new families of digital radio architectures. It describes advanced signal processing methods and evaluates algorithmic approaches by hardware platforms and associated measurements.
