Algorithm Driven System Selection with Reconfigurable Software Defined Radio in Mobile Devices

Emerging global standards for high-speed data, like WiMAX, WiBro, HSDPA and EVDO, presently provide islands of coverage. Such standards require new capabilities from mobile devices. With the coexistence of independent standards, protocols and services it is essential to develop wireless platform that can seamlessly connect to any access networks supported by different standards. Here proposed system architecture supports SDR among multiple communication standards. A logical interface between SDR subsystem and higher level protocol called system reconfiguration manager acts as a logical interface between SDR subsystem and user/application layer. Designed algorithm in SCM enables the proper selection of communication system e.g. OFDM, UMTS etc. and triggers for handover from one communication system to another when user/application specified requirements met by SDR subsystem.
