摘要 针对垂直分层空时(V-BLAST)结构,研究MIMO-OFDM系统的信号检测问题.根据矩阵伪逆的递推关系,提出了一种基于最大似然-排序串行干扰抵消(ML-OSIC)算法的简化处理方案,依次计算每一次迭代的迫零加权矩阵和加权向量.与传统的ML-OSIC算法相比,笔者给出的快速递归算法既可以基本保证检测算法的最优性,又能获得更快的处理速度和更低的计算复杂度. The problem of signal detection for MIMO-OFDM system by using V-BLAST is studied.A simplified treatment options based on ML-OSIC(maximum likelihood-ordered successive interference cancellation) algorithm is proposed in terms of a simple recursive relationship of computing pseudo inverses,so that the new zero-forcing(ZF) weight matrix and the corresponding ZF weight vector can be directly obtained by previous iteration value.Compared with the traditional ML-OSIC algorithm,the proposed fast recursive detection algorithm can not only guarantee the optimal detection performance,but also get faster processing speed and lower computational complexity.
