Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communications. SDR is viewed as an enabler of global roaming and as a unique platform for the rapid introduction of new services into existing live networks. It therefore promises mobile communication networks a major increase in flexibility and capability. SDR brings together two key technologies of the last decade - digital radio and downloadable software. It encompasses not only reconfiguration of the air interface parameters of handset and basestation products but also the whole mobile network, to facilitate the dynamic introduction of new functionality and mass-customised applications to the user's terminal, post-purchase. This edited book, contributed by internationally respected researchers and industry practitioners, describes the current technological status of radio frequency design, data conversion, reconfigurable signal processing hardware, and software issues at all levels of the protocol stack and network. The book provides a holistic treatment of SDR addressing the full breadth of relevant technologies - radio frequency design, signal processing and software - at all levels. As such it provides a solid grounding for a new generation of wireless engineers for whom radio design in future will assume dynamic flexibility as a given. In particular it explores* The unique demands of SDR upon the RF subsystem and their implications for front end design methodologies* The recent concepts of the 'digital front end' and 'parametrization'* The role and key influence of data conversion technologies and devices within software radio, essential to robust product design* The evolution of signal processing technologies, describing new architectural approaches* Requirements and options for software download* Advances in 'soft' protocols and 'on-the-fly' software reconfiguration* Management of terminal reconfiguration and its network implications* The concepts of the waveform description languageThe book also includes coverage of* Potential breakthrough technologies, such as superconducting RSFQ technology and the possible future role of MEMS in RF circuitry* Competing approaches, eg all-software radios implemented on commodity computing vs advanced processing architectures that dynamically optimise their configuration to match the algorithm requirements at a point in time The book opens with an introductory chapter by Stephen Blust, Chair of the ITU-R WP8F Committee and Chair of the SDR Forum presenting a framework for SDR, in terms of definitions, evolutionary perspectives, introductory timescales and regulation. Suitable for today's engineers, technical staff and researchers within the wireless industry, the book will also appeal to marketing and commercial managers who need to understand the basics and potential of the technology for future product development. Its balance of industrial and academic contributors also makes it suitable as a text for graduate and post-graduate courses aiming to prepare the next generation of wireless engineers.

Over the past few years software radio has transitioned from an esoteric academic idea to a rapidly commercialising technology that in the coming decade will revolutionise the mobile telecommunications marketplace. Written for industry professionals in engineering and commercial roles, as well as those in academia and research, this book will provide a comprehensive context for all those already active in or entering the field. Walter Tuttlebee, himself a pioneer of software radio in Europe, has gathered contributions from many of the acknowledged world experts in software radio -leaders operating at the heart of the software radio world today - who share their experience and insight into the background, the present and the future evolution of the technology and the industry. Contributions from North America, Europe and Asia ensure a comprehensive overview of the global SDR scene. The structured approach ensures that the book comprehensively addresses the key issues in the title - the origins of software radio, what has been (and is) driving its commercialisation and what is happening on the international sceneThe book includes: a comprehensive review of the origins of software radio in the defence industryan insider's view of the origins, evolution, role and activities of the SDR Foruma summary of the MIT Sloan study into the drivers of global success in the mobile wireless marketplacea review of end user and mobile network operator perspectives of software radio and what the value it can offerinsiders' summaries of recent SDR research activities in Europe and Japancoverage of the regulatory issues associated with SDR and the current approaches being taken in North America and Europe, with contributions from the regulators themselvesa description of the first steps to SDR standards - the ETSI MExE standarddescriptions of some of the first commercial software defined radio products, for both defence and commercial applicationsEndorsed with a foreword from Joseph Mitola III, 'the father of software radio'

The impending advent of GSM in the early 1990s triggered massive investment that revolutionised the capability of DSP technology. A decade later, the vastly increased processing requirements and potential market of 3G has triggered a similar revolution, with a host of start-up companies claiming revolutionary technologies hoping to challenge and displace incumbent suppliers. This book, with contributions from today's major players and leading start-ups, comprehensively describes both the new approaches and the responses of the incumbents, with detailed descriptions of the design philosophy, architecture, technology maturity and software support.
