Demodulation Soft Research of PCM/FM Signal in Reentry Telemetry Environment
SU Yong-he · Science Technology and Engineering · 2013
For reentry telemetry environment remote signal low signal noise ratio(SNR),and traditional demodulation method demodulation higher threshold,combined with PCM / FM signal phase characteristic,based on a symbol detection(MSD) software dissolve adjustment methods: continuous observed several element signal and local signal joint detection.And the corresponding synchronous demodulation algorithm ensure smoothly.Simulation and test results verify the effectiveness of the MSD.
