对并行级联空时格码(PC-STTC)与hybridARQ协议联合纠错方案的性能进行了研究.提出了并行级联空时码与hybidARQ结合的方案,采用turbo迭代译码方式,对于重发帧采用编码合并与最大比例合并(MRC)分集结合.通过montecarlo仿真,研究该方案在准静态平坦Rayleigh信道和平坦快衰落Rayleigh信道下的性能,并与另外两种方案进行吞吐效率对比.
The performance of joint error correction scheme with parallel concatenated space-time trellis code (PC-STTC) and hybridARQ protocol is studied.A scheme combining concatenated concatenated space-time code and hybid ARQ is proposed.The turbo iterative decoding scheme is adopted for retransmission The frame is encoded and combined with the maximum ratio combining (MRC) diversity.The performance of this scheme under quasi-static flat Rayleigh channel and flat fast-fading Rayleigh channel is studied by montecarlo simulation and the throughput efficiency is compared with the other two schemes.
