摘要

脉冲编码调制-调频(pulse code modulation-frequency modulation,PCM-FM)遥测系统因其具有很强的抗极化和系统抗干扰能力等优点被普遍用于军事卫星和航天遥测中,主要研究基于Turbo乘积码(Turbo product code,TPC)信道编译码技术下的PCM-FM遥测系统的实现与仿真,利用改进的Chase Ⅱ算法对系统进行解调,并通过对比发送端与接收端的信号,展现PCM-FM遥测系统调制与解调的正确性,以及改进的Chase Ⅱ算法对本系统的重要影响,通过模拟遥测信道验证所提系统的优越性能.

Abstract

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.
