| 摘 要： | 垂直分层空时码(VLST)是贝尔实验室提出的一种基于MIMO传输方式的空时码系统,其中,迫零检测算法(ZF)、最小均方误差检测算法(MMSE)和最大似然检测算法(ML)是常用的3种检测算法。着重对经典的ZF检测算法进行了深入的数学分析,并通过matlab仿真试验,给出了该算法在不同的调制方法、不同的信道估计误差下的性能分析,为构造实际VLST系统给出了理论依据

| Abstract: | Vertical Layered Space-Time Code(VLST) is a novel Multi-Input Multi-Output (MIMO) scheme based on the Bell Laboratories Layered Space-Time (LST) architecture.Among this,Zero-Forcing(ZF),Minimum Mean-Squared Error(MMSE) and Maximum Likelihood(ML) are three commonly used detection algorithms.An intensive mathematical analysis is taken on the classic ZF detection algorithm and the performance is analyzed under the different modulation method and the error of channel estimation via simulation experiments,which gives the theory basis for the actual VLST system. |
