摘要

本文研究多载波垂直分层空时(MC V-BLAST)系统的下行频率选择性衰落多输入多输出(MIMO)无线信道估计问题.本文首先为MC V-BLAST系统提出了一种新颖的移不变性编码方法.利用上述移不变性性质

本文进一步提出了相应的下行频率选择性衰落MIMO无线信道的盲估计方法.仿真结果表明了本文移不变性编码方法的有效性和信道盲估计方法的性能.

Abstract

The estimation problem of downlink frequency-selective fading multiple-input multiple-output (MIMO) wireless channels is investigated for the combination of the multicarrier (MC) technique with the vertical Bell Labs layered space-time (V-BLAST) architecture

i.e.

the MC V-BLAST system.One novel shift-invariance coding scheme is firstly proposed for the MC V-BLAST system.By exploiting the induced shift-invariance property

one blind estimation method of downlink frequency-selective fading MIMO wireless channels is further derived.Simulations demonstrate the validity of the shift-invariance coding scheme and the channels blind estimation method.
