摘要 对自动重传请求(HARQ)技术在时分双工、高速下行分组接入(TDD-HSDPA)系统中,特别是在采用了智能天线后遇到的一些特定问题进行了分析,提出了一种自适应编码与调制(AMC)和HARQ的融合方案.通过基于OPNET仿真软件搭建的系统仿真器,对算法进行了仿真研究,仿真结果表明,该方案可显著改善数据传输的可靠性,并能小幅度提升系统吞吐量. Unique problems that hybrid automatic repeat request （HARQ） encounter in time division duplex-high speed downlink packet access （TDD-HSDPA） systems are analyzed, especially when smart antennas are introduced. Accordingly, a novel mechanism combining HARQ with adaptive modulation and coding （AMC） is proposed. Dynamic system level simulator based on OPNET software is established to investigate the performance gain of the mechanism. Simulation results indicate that the scheme can reduce system block error rate （BLER） significantly and enhance system throughput.
