MF-TDMA卫星地球站信号处理流程及链路故障分析

Signal Processing and Link Fault Analysis of MF-TDMA Satellite Earth Station

MF-TDMA卫星通信系统组网灵活,支持综合业务接入,目前已成为国内外卫星应用、发展及研究的热点。在实际应用中,由于其组件的复杂性,导致应用中故障率相对较高。论文对卫星地球站及MF-TDMA体制卫通信号处理流程进行分析,提出了针对卫通地球站链路故障的处置思路,形成了卫通信信道链路中断处理流程图,基于MF-TDMA体制卫通链路常见故障点,根据信号处理原理解析其形成原因,并提出相应故障处置方法。

MF-TDMA satellite communication system supports flexible networking and multiple services transmission,it has become a hot pot in the development and research of satellite application at home and abroad.In actual application,the fault rate is relatively high because of the complex module of the system.This thesis proposes processing flow charts based on the analysis of MF-TDMA satellite communication system link faults.Faults processing methods also proposes according to the practical expriences based upon common fault.
