Abstract :
Software radios have been widely studied as a solution to support multiple air interface standards in future wireless communications. In this paper, we present an efficient IF processing architecture for a dual-mode GSM/W-CDMA terminal based on the concept of software radio. Simplified digital mixer, high decimation rate filter and fractional frequency conversion techniques are adopted in this architecture to make it compatible with both GSM and W-CDMA. Simulation results show the performance of the architecture is suitable
