摘要 把垂直分层空时码(Vertical-Bell Laboratories layered space-ti me,V-BLAST)中常用检测算法按照基于迫零(Zero-Forcing,ZF)和最小均方误差(Mini mum Mean Square Error,MMSE)分类并进行对比研究,通过MATLAB仿真分析各种算法的性能,结果表明,基于MMSE的检测算法明显优于基于ZF的检测算法。因此,基于MMSE的检测算法更适合V-BLAST。 The common detection algorithms of V-BLAST（Vertical-Bell Laboratories layered space-time） are classified by whether they are based on ZF（Zero-Forcing） or MMSE（Minimum Mean Square Error）,and their performance are contrastively analyzed with the help of MATLAB.Simulation results show that,the detection algorithms based on MMSE are obviously better than the algorithms based on ZF.Therefore,the detection algorithms based on MMSE are more suitable for V-BLAST.
