SDR brings together two key technologies of the last decade - digital radio and downloadable software. The book is edited, contributions from internationally respected researchers and industry practitioners, describes the current technology status of radio frequency design, data conversion, reconfigurable signal processing hardware, and software issues at all levels of protocol stack and network. This book provides a holistic treatment overcoming SDR full breadth of relevant technologies - radio frequency design, signal processing and software - at all levels. Specifically discuss The uniqueness of the demands of SDR on the RF subsystem and their implications for front end design methodology Recently, the concept of 'digital front end' and 'parametrization' The role and influence of major data conversion technology and devices within software radio, it is important to design a robust product Evolution of signal processing technologies, describing new architectural approaches Requirements and options for download software Progress in the 'soft' protocol and 'on-the-fly' reconfiguration of software Management of terminal reconfiguration and network implications The concept of wave description language The book also includes coverage The potential breakthrough technologies, such as superconducting RSFQ technology and possible future role in RF MEMS circuits Competing approaches, such as the radio all the software-implemented on commodity computing vs advanced processing architectures that dynamically optimize their configuration to suit your needs at this point in time algorithm The book opens with introductory chapter by Stephen Blust, Chairman of ITU-R WP8F Committee and Chairman of the SDR Forum provides a framework for the SDR, in terms of definition, an evolutionary perspective, the time span and the introduction of regulation. Suitable for today's engineers, technical staff and researchers in the wireless industry, this book will also appeal to marketing and commercial managers who need to understand the basics and potential of technology for future product development.
