Software Defined Radio

Software defined radio (SDR) is a hot topic in thetelecommunications field, with regard to wireless technology. It isone of the most important topics of research in the area of mobileand personal communications. SDR is viewed as the enabler of globalroaming and a platform for the introduction of new technologies andservices into existing live networks. It therefore gives networks agreater flexibility into mobile communications. It bridges theinter-disciplinary gap in the field as SDR covers two areas ofdevelopment, namely software development and digital signalprocessing and the internet. It extends well beyond the simplere-configuration of air interface parameters to cover the wholesystem from the network to service creation and applicationdevelopment. Reconfigurability entails the pervasive use ofsoftware reconfiguration, empowering upgrades or patching of anyelement of the network and of the services and applications runningon it. It cuts across the types of bearer radio systems (Paging tocellular, wireless local area network to microwave, terrestrial tosatellite, personal communications to broadcasting) enable theintegration of many of today's disparate systems in the samehardware platform. Also it cuts across generation (second to thirdto fourth). This volume complements the already published volumes 1and 2 of the Wiley Series in Software Radio. The book discusses therequirements for reconfigurability and then introduces networkarchitectures and functions for reconfigurable terminals. Finallyit deals with reconfiguration in the network. The book alsoprovides a comprehensive view on reconfigurability in three veryactive research projects as CAST, MOBIVAS and TRUST/SCOUT. Key features include: * Presents new research in wireless communications * Summarises the results of an extensive research program onsoftware defined radios in Europe * Provides a comprehensive view on reconfigurability in threevery active research projects as CAST (Configurable radio withAdvanced Sodftware Technology), MOBIVAS (Downloadable MOBIle ValueAdded Services through Software Radio and Switching IntegratedPlatforms), TRUST (Transparently Re-configurable UbiquitousTerminal) and SCOUT (Smart User-Centric CommunciationEnvironment).
