摘要 介绍了无线城域网协议中的前向差错控制4种方案,建立了一个无线城域网下行链路仿真系统,对单载波模式不同码率的TCM和RS-TCM两种方案进行仿真分析,对OFDM(A)模式下的RS-CC、BTC、CTC 3种编码方案进行仿真和性能分析,给出了其中较优的差错控制方案,为实际应用提供了重要的参考。 This paper introduces the FEC system of wireless-MAN(WMAN) standards. Several feasible schema are compared. A simulation system of the downlink of WMAN is constructed for performance analysis. The performance of FEC is analyzed, and the best scheme is presented. The analysis will be an important reference for project application.
