摘　　要：垂直分层空时码(V-BLAST)是贝尔实验室提出的一种多天线(MIMO)结构无线通信系统。近年来,由于该系统具备较高传输容量和频谱利用率,而受到了广泛关注。文章详细介绍了V-BLAST的系统模型、信道容量和常用的接收端检测算法,分析了各种检测算法的特点和性能,并逐一给出了仿真结果。许多学者已将V-BLAST系统的研究推广到了实际应用领域,使之成为未来移动通信的一个重要分支。Vertical Bell Laboratories Layered Space-Time coding (V-BLAST) is a multi-input multi-output (MIMO) wireless communication architecture proposed by Bell Lab. Because of its high capacity and large spectral efficiency, V-BLAST system became popular in recent years. In this paper, the system model, transmitting capacity and the detection algorithm of V-BLAST are introduced, the characteristic and performance of typical algorithm are analyzed, and the simulation results are given out. The research of V-BLAST system has been popularized to the actual application, and makes it to be an important branch of mobile communication in the future.
