摘要 Nguye Thi和Jutten提出了几种在卷积混合情况下基于四阶互累积量的信号盲分离算法。对这些算法的稳定性进行了分析研究,主要分析算法1和算法2的稳定性。计算机仿真实验结果表明,算法1不稳定,不能正确收敛到正确的分离矩阵,只有算法2有较好的稳定性。 NguyeThi and Jutten have proposed the algorithms for separating the signals of convolutive mixtures based on 4thorder cumulants. In this paper, the stability of the algorithms is studied. It is shown that not all the algorithms can converge to the proper separation matrix and only one can converge to the right solution.
