摘　　要：空时分组码能够提供分集增益,但是不能提供编码增益,为了提高空时分组码的可靠性能,本文提出一种高速卷积空时分组码的设计方法。该方法将高速空时分组码和删余卷积码进行级联,既保证了传输速率又提供了编码增益。Space--time block codes （STBC） provide diversity but have little or no coding gain. In this letter, A high rate concatenated space--time block codes and convolutinnal codes is proposed, which enjoying punctured convolutional codes as outer code and employing STBC as the inner cede. The proposed scheme provides coding gain as also as high rate.

关 键 词：MIMO 空时分组码 级联 删余卷积码
