| Abstract(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 sources 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 signals. The separation matrix obtained in Permutation-Free ICA, however, has common directivity for all frequency bins. Presented in this report is a new method that generates a separation matrix for each frequency bin, based on a simplified mixing model having no permutations, retaining high processing speed. |
