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