摘要
垂直分层空时码(V-BLAST)是贝尔实验室提出的一种基于多入多出(MIMO)传输方式的空时码系统,其检测算法是MIMO系统的有效检测方法。首先介绍了V-BLAST系统的信号模型,在此基础上应用不同的信号估计准则推导出不同的检测算法,最后通过仿真实验对各种算法的性能和优缺点进行了分析和比较。
Vertical Bell Layered Space-Time Code(V-BLAST) is a novel Multi-Input Multi-Output(MIMO) antenna scheme based on the Bell Laboratories Layered Space-Time(BLAST) architecture.Its detection algorithm is the effective detection method for MIMO system.Firstly,this paper introduces the V-BLAST system signal model and then educes several detection algorithms with applying different signal evaluation rules.Finally,this paper analyzes and compares the performance and characteristics between these algorithms through simulation results.
