摘　　要：考虑到正交空时分组码可提供满分集增益,以及垂直多层空时分组码能达到较高的数据传输速率,借鉴Tarokh构建基于天线分组的多层空时编码方法,本文提出了一种能根据接收信噪比自适应选择空时编码调制方式的MIMO传输方案,并给出了Monte-Carlo仿真与理论分析。仿真结果表明,在一定的信噪比范围内,方案在保证低误码率的条件下达到数据速率的最大化。According to the facts that the orthogonal space time coding （OSTBC） can provide full-diversity and that the multi-layered space-time coding （V-Blast） can achieve very high transmission data rate, and referring to the construction of antenna groups by Tarokh, a method called adaptive multi-layered space-time coding using SNR as thresholds is proposed. Monte-Carlo simulation and theoretical analysis are given. The simulation result method can maximize the data rate under specific level of symbol error rate （SER）in a certain SER range
