FM Stereo Receiver Based on Software-Defined Radio

The paper proposes the FM stereo receiver based on Software-defined Radio by FPGA devices, according to the theories of multi-rate digital signal processing and switching means FM stereo decoding. Through the extraction and half-band filter to achieve down-sampling, the digital phase-locked loop extracted pilot signals and achieve the stereo decoding based sub-carrier switch signal. This paper simulates the performance of the receiver in MATLAB Simulink environment and FPGA emulation mode. The simulate results and Signal TAP waveforms show that the method can effectively achieve the FM stereo demodulation.
