| Abstract(in English) | In several types of Blind Source Separation (BSS), the convolutive Blind Source Separation remains a difficult problem. Frequency Domain Blind Source Separation (FD-BSS) is known as one way to solve the convolutive BSS, in which we apply short time Fourier transform on observation signals and apply common BSS or ICA on each frequencies. Generally, FD-BSS has so called permutation problems. In this paper, we propose a new method to solve the problem according to the linearity of the phase shift on the frequencies. To estimate the angle of the linearity, we apply the Hough transform so that we do not need to care about direction of arrival nor spatial aliasing. |
