Research on Demodulation of High Bit Rate Telemetry Signal in FM Baseband

Abstract:

According to the characteristics of PCM / FM signals, we propose a new software-based STFT Demodulation algorithm. This paper discusses in detail the basic principles of this demodulation algorithm and implementation process, analyze the complexity of the algorithm, proposed a new method for the extraction and correction code synchronization. Simulation results show that the algorithm not only can effectively suppress the influence of various disturbances in the actual signal synchronization accuracy of the code, with better demodulation performance, and realization of the principle is simple, high efficiency, easy to implement software-oriented real-time treatment.
