Abstract :
Software-defined radio (SDR) is a rapidly evolving technology. SDR have been widely studied as a solution to support multiple competing and in compatible air interface standard in future wireless communications. In this paper, we present the design of a digital down converter (DDC) module for triple-mode WCDMA, CDMA2000 and GSM. The designed module consists of digital mixer, CIC filter, and decimation filter and frequency converter. Theses sub-modules are software reconfigured in architecture to be compatible with WCDMA, CDMA2000 and GSM. The design is software configured with minimum hardware and maximum operating speed.
