摘要:现有的盲分离算法绝大部分是独立分量分析法,然而在实际应用中,独立分量分析法有诸多的限制条件。针对该问题,本文提出一种基于独立因子分析法(Independent Factor Analysis,IFA)的信号盲分离算法。独立因子分析法结合了一般的因子分析法、主元分析法以及独立分量分析法的优点,用于解决混合语音信号的盲分离问题。实验结果证明:独立因子分析法可以处理信源数目不同且数据包含强噪声的情况。数据信噪比越低,独立因子分析法的优势更为显著。
Most of the existed algorithms on BSS (Blind Signal Separation) are based on ICA (Independent Component Analysis). However, ICA has many limits problem, a new BSS algorithm based on IFA (Independent Factor in actual Analysis) IFA generalizes and unifies ordinary factor, principal component analysis use. In order to solve this was proposed in this paper. and ICA. It is proved by the simulation result that IFA can handle the case that the number of mixtures differs from the number of sources and the data include strong noise. The lower is SNR of data, the better is the predominance of IFA.
