摘　　要：介绍了空时信道模型,表述了空时网格码的设计准则,构造了最佳空时网格编码M-PSK方案,该方案适用于慢衰落和快衰落信道的各种发射天线数和频谱利用率;最后给出了空时网格码的译码方法。In this paper, we firstly introduce the models of space-time channels and formulate the design guideline of space time code （STC）. Based on the rationale mentioned before, we construct the encode schemes of all kinds of modulation systems which are applicable to different numbers of transmitting antennas and spectrum utilization ratio both for fast-fading channel and slow-fading channel.
