Research On Software Radio Technology In Base-band Signal Processing

This paper deals with software radio base band signal processing based on the FPGA, proposes the method by choice different software to realize software and hardware model according to the radio duty attribute, designs the hardware structure and the electric circuit of software radio receiver, and obtained the certain research results. Attention is concentrated on the realization of the software radio signal processing such as modulate and demodulate which after the intermediate frequency conversion and A/D by FPGA. The simulations and synthesizes have been carried out using MODELSIM, SYNPLIPY and MATLAB.Studies have shown that what we do suits the development and application demand of the software radio technological in the future, and provide a general platform for signal processing in the base band;also have the certain reference value to the next research.
