摘要: 为了获得高码率低时延的多天线复正交空时分组编码矩阵，该文提出了一种未对信号进行线性处理的复正交空时分组编码矩阵的迭代式设计方法。利用该矩阵良好的正交性发射的信号，在接受端可以通过简单的最大似然解码算法来准确还原。借助计算机的帮助，得到该方法设计的多天线复正交空时分组编码矩阵的数据，与其他设计方法得到的复正交空时分组编码矩阵的数据进行了比较，结果显示该矩阵在最大码率和最小解码时延上封闭。

Abstract: For construct a high-rate and low-delay Complex Orthogonal Space-Time Block Codes (COSTBC) matrix, this paper presents an iterative design method without linear processing of symbols to generate high-rate and low-delay COSTBC matrix. By the orthogonality of symbols, a simple maximum likelihood-decoding algorithm is used to recover them at the receiver accurately. By the help of computer, the data of the matrix are got. The results of compare the data with that from others matrix shows the matrix is a closed-form design of high-rate and low-delay. -
