| Abstract: | The presented blind source separation algorithms are very complicated for the hardware with the real-time operation. According to the principles and characteristics of the blind source separation, a real-time blind speech separation algorithm which can improve both the separation speed and the separation performance is proposed. The simulating results show that the proposed algorithm is effective. |
