摘　　要：对多输入多输出系统中垂直分层空时检测算法常用的最小均方误差算法、迫零检测算法、非线性检测算法以及正交三角分解检测算法进行分析比较.仿真实验结果表明:在相同天线系统下,经过排序串行干扰消除的最小均方误差检测算法性能最优.In this paper,the commonly used minimum mean square error algorithm,zero-forcing detection algorithm,nonlinear detection algorithm and orthogonal triangular decomposition detection algorithm in the vertical layered space-time detection algorithm were analyzed and compared in the multiple input-multiple output system.The experimental results showed that after ordering serial interference cancellation the minimum mean square error detection algorithm performed best in the same antenna system.
