摘　　要：应用最大最小原理实现了广义正则形式的最小方差空时多用户检测,并采用多级维纳滤波结构提出了一种新的低秩处理算法。进一步与现有的几种低秩处理算法进行了比较,分析了秩的选择对系统性能的影响。In this paper the minimum variance space-time multiuser detection with the generalized canonical representation is implemented by the max/min principle. Furthermore, a new low-rank algorithm is proposed based on the multistage Wiener filtering. Finally, it is compared with the existing low-rank algorithms and the effects of the rank selections on performance degradation are analyzed.
