摘要
提出了一种新的基于子空间的盲信道估计方法。该方法利用时序反转空时分组编码,运用"虚拟接收天线"的方法进行盲信道估计,在一定程度上克服了传统的基于子空间的信道估计算法对MIMO系统中输入输出天线数目的要求限制。仿真结果证明了此方法有较好的信道估计性能。
A novel subspace-based blind channel estimation method is proposed in this paper, in which Time-Reversal Space Time Block Coding（TR-STBC） is employed and the conception of ＂virtual receive antenna＂ is proposed. This method improves the traditional subspace-based method to a certain extent. Simulation results demonstrate the effectiveness of this method.
