This paper describes the development of an SDR (software defined radio) platform for use in investigating the requirements for implementing many popular standards such as GSM, WiFi and 3G through SDR. The first stage of this work is to generate specifications for an SDR implementation from various wireless standard requirements. The next stage is the development of suitable reconfigurable hardware. The final stage is the development of suitable software for the reconfiguration of the hardware and the implementation of the standards. Â© 2007 IEEE.
