이진 마스크 기반 Blind Source Separation을 위한 베이스 시간-주파수 포인트 추정 방법 비교Comparison of Base Time-Frequency Points Estimation Methods for Blind Source Separation Using Binary Mask
In the case of speech signal, a large portion of signal energy is concentrated on a small number of time-frequency points. Based on our assumption that the points that contain a large portion of each signal do not overlap, we compare three kinds of base time-frequency points estimation methods for blind source separation. And the experimental results are described.
