Abstract :
Programmability of the baseband receiver hardware will be essential in the future as multiple radio technologies need to be supported by the mobile terminal. A programmable coprocessor architecture is presented in this paper that can be used to implement demodulation procedures of WCDMA and OFDM receiver. The coprocessor architecture is presented and the programming interface designed for the coprocessor is explained in detail. Simulation and synthesis results are also given.
