基于MMSE-SQRD的V-BLAST系统检测算法研究与仿真

摘要

MIMO系统可以增加通信容量和频谱利用率,传统的检测V-Blast架构系统的算法无法很好的兼顾检测的性能和复杂度.本文提出了一种检测V-Blast系统的Sort-free QRD-M算法,阐述了其基本原理和搜索方式,对其和其它检测算法的检测复杂度和检测性能进行了仿真分析和对比.%Vertical Bell labs layered space-time Code is a space-time system based on multi-input multi-output transmit system, the detection algorithm of which is effective for MIMO system. The traditional detection algorithms of V-Blast can not balance the performance and the complexity. The sort-free QRD-M algorithm is put forward in this paper, the principle and searching mode was expounded, the performance and complexity of this algorithm and other algorithms were contrasted.
