Abstract :
This work deals with software radio design and optimization for the IF section of a GSM transceiver based on a GMSK modem. To accomplish the tight real-time requirement, for the modem, with a low-cost device, we propose a methodology approach for the implementation by looking for the optimum use of DSP architecture parallelism. Experimental results with a fixed point 16-bit DSP are presented to show the efficiency of the optimized GMSK software modem
