摘要/Abstract

摘要： 对并行级联空时格码(PC-STTC)与hybrid ARQ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hybid ARQ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monte carlo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。

关键词: 空时格码, 并行级联码空时码, turbo

Abstract: The performance of parallel concatenated space time trellis code (PC-STTC) in conjunction with Hybrid ARQ protocols is investigated.The scheme to combine PC-STTC with Hybrid ARQ is proposed, in which turbo iterative decoder combines code diversity with MRC diversity for the retransmitted frames. The performance of the scheme in quasistatic flat Rayleigh channel and that of flat fast Rayleigh channel is studied by the monte carlo simulation.

Key words: space time trellis code (STTC), parallel concatenatedspace time trellis code (PC-STTC), turbo
