According to the characteristics of PCM/FM signal demodulation, the research based on short-time Fourier transform STFT software resolving method. First detected using STFT f1 and f0 corresponding spectrum energy, according to the comparison of two energy spectrum of element. Software demodulation system is discussed in detail the synchronous digital detection and software algorithms, analysis of demodulation performance of the algorithm. The simulation and test results verify the effectiveness of the method.
