This paper proposes a reconfigurable platform for software/hardware co-design of base band pre-processing module of wideband wireless transceivers. The platform uses the Digital Signal Processors (DSP) and Field Programmable Gate Array (FPGA) to run advanced digital signal processing algorithms intended for the performance optimization of the transceiver radiofrequency front-end. Having the possibility to generate a variety of modulation techniques at high sampling rates and wide bandwidth up to 60MHz, the proposed platform is suitable for implementing innovative software defined radio transceivers' base band modules including digital pre-processing algorithms to boost the transceivers performances. An implementation and validation approach is also proposed. Taking advantage from the communication protocol between the DSP and the FPGA, the validation is done using the DSP it self for acquiring digital data at the output of each hardware function. A comparison of the emulation results to the high-level simulation ones is used to validate the hardware implementation and debug eventual bugs.
