Simulation and Implementation of PCM-FM Telemetry System Based on TPC Code
The PCM-FM(pulse code modulation-frequency modulation)telemetry system is widely used in military satellites and aerospace telemetry owing to its exceptional polarization resistance and robust anti-interference capabilities.The implementation of the PCM-FM telemetry system was focused based on TPC(Turbo product code)channel coding technology.The improved Chase Ⅱalgorithm was employed for demodulating the system,and it was compared with a baseline algorithm and the theory model to evaluate its performance.The results show that the proposed Chase Ⅱ algorithm has a lower error rat then the baseline algorithm and close to the theoretical model.The accuracy of the improved algorithm is verified through network simulations.
