This work focuses on a new digital radio architecture now emerging as a key technology in the wireless industry and in the third generation of cellular communication. This book addresses the problems of wireless high data rates from a physical layer point of view and presents an innovative approach from both a theoretical and practical point of view. The author explains the fundamental theory for the transmission of digitally modulated signals with and without antenna arrays, details new families of digital radio architectures, describes advanced signal processing methods and evaluates algorithmic approaches by hardware platforms and associated measurements. A reference and research tool, this book should enable professionals 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.
Broadband wireless access; theoretical limits of the spatio-temporal wireless channel; digital radio design principles; space-time modems based on traditional principles; spatio-temporal processing using high-order statistics; an experimental digital radio for MIMO; advanced solutions for high mobility; spatio-temporal radios for CDMA.
