MIMOOFDM系统中基于独立分量分析的盲信道估计算法研究

Study on ICA Based Blind Channel Identification in MIMO OFDM Systems

研究了MIMOOFDM系统基于独立分量分析（Independent Component Analysis）的盲信道估计算法，提出了改进的ICA-only算法。该算法将ICA算法应用到各个子载波，将ICA算法所固有的排列和幅值上的模糊性通过发射端的线性编码来消除，实验结果表明，该算法能很好地估计出信道参数。

In this paper, one ICA-based blind channel identification algorithms in MIMO OFDM systems are proposed. It is the ICA-only algorithm. The ICA-only method proposed in this paper obtains better performance by using ICA in every subcarrier.
