| Abstract: | 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. |

| Keywords: | ordering serial interference cancellation minimum mean square error zero-forcing detection orthogonal triangular decomposition |
