摘　　要：在多输入多输出(MIMO)通信系统中,MIMO检测是发送端MIMO编码的逆过程,是根据接收到的信号及接收信号质量、信道状态信息等获得发送端发送比特的概率信息过程。通信信道矩阵的QR分解(QRD)是几种MIMO信号检测方案的基本先决条件。首先针对QRD方案进行研究,详细介绍了QRM-MLD的算法实现并进行了优化。最后对复杂度进行了统计并对仿真结果进行了分析,证明此方案可以作为MIMO检测的优选方案。In MIMO （ multi -input multi - output） communication system, MIMO detection is the reverse process of MIMO coding, and from the received signal and its quality and channel status information it ob- tains the bits probability information of the transmitter. The QRD （ QR decomposition） of communication channel matrices is a fundamental prerequisite for several detection schemes. Firstly, the QRD methods are studied. Then the realization procedure and optimization of QRM-MLD are described in detail. Finally, the statistics of the complexity are presented, the simulation results are analyzed. It is verified that this so- lution can be used as a preferred scheme of MIMO detection.
