Soft Demodulation of PCM/FM Signal Based on MSD Research

Abstract:

To improve the performance of the system PCM/FM, this paper used the multi-symbols detection (MSD) technology. Firstly PCM/FM in hardware demodulation in a series of problem, introduces MSD software demodulation method. Then the MSD in low SNR environments of a synchronous implementation. The algorithm simulation indicates that the detection performance than the traditional incoherent algorithm is popularly used increased nearly 3 dB at the bit error rate in 10-4 place. Performance is very ideal.
