Beschreibung
Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communication. 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.
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
* management of terminal reconfiguration and its network implications
* the concepts of the waveform description language
* 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
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 postgraduate courses aiming to prepare the next generation of wireless engineers.
Contributed by internationally respected industry practitioners and researchers this book provides a holistic treatement of SDR addressing the full breadth of relevant technologies - radio frequqncy design, data conversion, reconfigurable signal processing hardware, and software issues at all levelsof the protocol stack and network. As such it provides a solid grounding for a new generation of wireless engineers for whom radio design in the future will assume dynamic flexibility as a given.
Im Mittelpunkt dieses zweibändigen Werkes stehen Funkdienste, bei denen die Wellenformen zur Kanalmodulation durch eine Software definiert werden (SDR). Dadurch kann der Service Provider die Funktionalität eines Empfängers für neue Dienste aktualisieren und konfigurieren, ohne daß es der Benutzer merkt. Ermöglicht wird durch diese Technologie unter anderem Global Roaming. SDR ist ein interdisziplinäres Arbeitsgebiet, das Softwareentwicklung und digitale Signalverarbeitung miteinander verbindet. Band 1 des Werkes, verfaßt von Forschern und Entwicklern aus der Industrie, beschreibt den aktuellen technischen Stand von SDR (darunter HF-Design, Signalverarbeitung und Middleware) und schließt damit eine Lücke zwischen spezialisierten Informationsangeboten zu den einzelnen Gebieten. Behandelt werden Protokolle, Signalisierung und Schnittstellen zu Anwendungsprogrammen.
