An open software-radio architecture supporting advanced 3G+systems

This paper describes a software-radio architecture developed for providing real-time wide-band radio communication capabilities in a form attractive for advanced 3G systems research. It is currently being used to implement signaling methods and protocols similar; bur not limited to, evolving 3G radio standards (e.g. UMTS, CDMA2000). An overview of the hardware system is provided along with example software implementations on both high-performance DSP systems and conventional microprocessors.
