中文摘要：
在两跳协作通信中,第一跳增益来自接收分集,第二跳主要增益来自协作编码.利用协作中继节点的多天线构成的MIMO系统,构造一种新型的连续STBC编码,VBLAST-STBC混合解码的中继HARQ策略,可以同时有效获得HARQ的时间分集增益以及空时编码的分集增益与复用增益.理论分析与仿真结果表明,Relay-STBC-HARQ策略可以充分挖掘第一跳的分集增益以及第二跳的协作增益,不仅可以获得可靠性覆盖,而且可以在误码率、码率与时延间获得一种弹性平衡.
英文摘要：
In 2-hop relay communication system, the first hop mainly gets the diversity gain while the second hop gets the cooperative gain. While the HARQ can get the time diversity gain, space-time block coding can get a trade of diversity gain and multiplex gain, it is significant to combine the HARQ and STBC in a cooperative MIMO system that multi-antenna come from cooperative relay nodes. According to analysis the relationship between the VBLAST, HARQ and STBC, a novel Relay-STBC-HARQ was proposed. The algorithm performs well in the performance simulation that can improve the system capacity by spatial multiplex gain and cooperative gain. This means credible coverage and a flexible tradeoff among BER rate, code rate and delay.
