Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we discuss microphone location and the separation method using frequency-domain independent component analysis aiming to high-performance source separation with distributed microphone arrays. In the distributed microphone array framework, which has the advantages of
its abilities to separate wide-spread sources, simplify hardware configurations and make it easy to increase devices, we discuss 1)the time alignment of each channel using cross correlation, 2)permutation correction with distributed microphone pairs and 3)designing of post-filter based on the uncorrelatedness of diffuse noises. The experimental results in real reverberant environment are also shown.
