基于PPM硬判决的ARQ-FSO系统误码性能分析
2017
Overview
TN929.1; 基于PPM(Pulse Position Modulation)硬判决检错的ARQ-FSO(Automatic Repeat Request-Free Space Optical)通信系统结合了PPM硬判决和新的ARQ协议.该系统以PPM硬判决的结果代替了传统ARQ的监督码元作为数据的检错依据,同时只重传数据包里面译码失败部分的PPM符号,消除了传统ARQ中用来检错的信息冗余,提高了系统的效率.理论分析表明该方案能够有效地改善硬判决误码率,其通过率也优于传统ARQ,适用于较低误码率、低复杂度的自由空间光通信场景.
