摘要：
It is well known that Independent Component. Analysis (ICA) is a useful method for blind source separation although it does have some drawbacks, such as performing poorly on unsteady sounds. In this study, in order to improve this de deficiency, a new method combining ICA with the cony-Vex discrete wavelet transform is proposed and verification of source separation with relation to the problems of permutation and scaling in the ICA are performed Through comparison of the results according to the Signal Noise Ratio (SNR), the effectiveness of the proposed method is confirmed.
