| 摘 要： | 针对MIMO-OFDM系统,提出了一种基于子空间的盲信道估计与检测方案,该算法将阵列信号处理的思想应用到MIMO-OFDM系统中,通过发送端信号的冗余编码,利用一种类ESPRIT算法进行盲信号检测和信道估计。仿真结果表明该算法的有效性及其信道盲估计方法的性能。

| Abstract: | Based on the subspace technique,a blind channel estimation algorithm for multiple input and multiple output orthogonal frequency division multiplexing(MIMO OFDM) systems is discussed on in this paper.The algorithm applies array signal processing technology in MIMO OFDM systems.Using redundant precoding of the signals transmitted,an ESPRIT-like blind subspace channel estimation algorithm is presented.The theoretical analysis is provided to show that the channel responses of the system can be identified blindly via the proposed method,and Monte Carlo simulations are employed to indicate the channel estimation performance. |
