Abstract (in Japanese) (See Japanese page) 
(in English) Permutation-Free ICA is a method that can avoid so-callled “Permutation problem” that appears in conventional frequency-domain ICA due to indeterminicity among source identity in each frequency bin. Permutation-Free ICA carries out separation on a set of long vectors consisting of connected temporal changes of frequency components of the received signal. The separation matrix obtained in Permutation-Free ICA, however, has common directivity for all frequency bins. Applying Wiener Filter on a resultant signal of Blind Source Separation, frequency characteristics of the separation matrix are thought to be taken into account. In this paper, effects of applying Wiener Filter after Blind Source Separation are evaluated using segmental SNR and PESQ as evaluation indeces.
