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。
In order to solve the problem of the uncertainty of the order of signal connection between the output signal frame and the frame in blind source separation, an iterative algorithm of optimal separation matrix iteration algorithm is proposed. The separation matrix of the objective function in each signal separation is taken as the next frame cycle The initialization matrix iterates to separate the signal. Theoretical analysis and computer simulation show that this algorithm can effectively solve the uncertainty of signal order in blind separation and has strong practical value.
