摘要
混合自动请求重传(HARQ)以ARQ方式合并带有前向纠错码(FEC)的数据包,明显地提高系统的吞吐量。围绕无线通信系统中几种MIMO-HARQ合并方案,从存储要求、误码率等多角度考虑接收机的设计。提出了一种新的接收机合并方案,分析和仿真表明,所提方案具有很好的误码率性能与存储要求之间的折中,可应用于Chase合并和增量冗余合并中。
Hybrid automatic repeat reQuest （HARQ） improves the throughout of ARQ by combining retransmission of packets with forward error correction（FEC） coding. This paper focuses on wireless communication systems using some HARQ-MIMO combin- ing schemes, and designs the architecture of receiver from memory requirements and BER performance. A novel receiver combining scheme is proposed. With the analyses and the simulations, the proposed scheme has good tradeoff of BER performance and memo- ry requirement. It can be applied in MIMO-HARQ systems with either Chase combining or incremental redundancy （IR） combining.
