| 摘 要： | 为了选择适当的算法以降低垂直分层空时码(Vertical-Bell Laboratory Layered Space-Time,V-BLAST)系统的检测复杂度,提高系统性能,介绍迫零、最小均方误差、排序的QR分解和排序的最小均方误差串行干扰抵消算法,并借用MATLAB软件对它们的性能进行仿真分析。结果显示排序的最小均方误差串行干扰抵消算法的性能最优,但算法中加入了排序和矩阵求逆,增加了复杂度;迫零算法的复杂度最小,但性能很差。排序的比非排序的检测算法的性能好,同时复杂度会增加.

| Abstract: | To reduce the V-BLAST(Vertical-Bell Laboratory Layered Space-Time) system complexity and improve system performance,several classical algorithms for V-BLAST systems,such as ZF(Zero Forcing),MMSE(Minimum Mean Squared Error),the ordered QR decomposition detection algorithm and MMSE-OSIC,are introduced and their performance are analyzed with the help of MATLAB.Simulation results show that,MMSE-OSIC performs the best;ZF is of the lowest complexity;a detection algorithm based on ordering performs better than tho... |
