| 摘 要： | 讨论一种非平稳卷积混合声音信号盲分离算法。该算法基于多时延解相关准则建立代价函数，用Frobenius范数最小化代价函数得分离矩阵。算法计算量低，适用于自适应在线运算，而且不要求时延相关矩阵是正定的。对非平稳卷积混合声音信号进行仿真实验，验证了算法的有效性。

| Abstract: | This paper discusses a blind separation algorithm of non-stationary convolved sounds mixtures. A cost function is built on multiple timedelay decorrelation rifle, the separation algorithm is obtained by minimizing the cost function , using the Frobenius norm. The algorithm has low computing cost, more adapt to on-line blind separation and the time delayed correlation matrix is not necessarily positively definite. Simulation confirms its validity for non - stationary convolved sounds mixtures. |
