摘　　要：针对盲源分离后信号存在排序和相位不确定性的情况,提出一种基于相关系数的盲源分离排序和相位调整法,通过对盲源分离后信号运用该方法进行排序和相位调整,从而消除盲源分离后信号存在的相位和排序不确定性。仿真结果表明,在混合矩阵主对角线元素占优的情况下,此法可以有效地消除盲源分离后信号存在的排序和相位不确定性。In allusion to the signals by blind source separation have incertitude in the sequence and pnase,a memoa ior adjusting the sequence and phase based on correlation is presented. It can eliminate the incertitude of signals which is separated by blind source separation in the sequence and phase by using the method based on correlation to adjust the sequence and phase. The results of blind source separation for the data show that the method based on correlation is an effective method in eliminating the incertitude of signals when the elements on main diagonal line in the mixed - matrix are in the ascendant.
