| 摘 要： | 文章针对盲源分离中输出信号帧与帧之间信号衔接顺序的不确定性问题,提出了最优分离矩阵循环迭代算法,将每帧信号分离时目标函数寻优所得分离矩阵作为下一帧循环的初始化矩阵进行迭代来分离信号。理论分析与计算机仿真表明:该算法能有效解决盲分离中信号次序的不确定性问题,具有较强的实际应用价值。

| Abstract: | In order to solve the problem that the permutation of output signals in blind source separation is uncertain,we propose an algorithm based on the iteration of the optimal separation matrix.We use the last optimal separation matrix to initialize the separation matrix of the new frame.Theoretical analysis and computer simulation show that the algorithm can effectively solve the uncertainty of order in blind signal separation and has high application value. |
