摘要: 基于错误归类的思想,提出了一种在准静态瑞利衰落信道下改进的空时格码设计准则。基于这个准则,给出了一种有效的、直接的计算机穷尽搜索的码构造方法。这种构造方法大大减小了计算量。

Abstract: A modified criterion for quasi-static rayleigh fading channels is presented with classification of error events. Based on the criterion, an effective and straightforward method is proposed to construct codes withbetter performance by search. This method has better advantage not only on computation but also on performance.

Key words: MIMO, space-time trellis codes(STTC), design criteria
