| Abstract(in English) | Blind source separation (BSS) is a technique for estimating original source signals using only sensor observations that are mixtures of the original signals. We discuss frequency-domain 1CA (FDICA). Because FDICA has an advantage that mixtures regard convolutive case as instantaneous one. Two kinds of arbitraries are generated in BSS, because of evaluating only the statistical independency of signals. One of arbitraries is Scaling and the other is Permutation. By these arbitraries, separated signals will become distorted.In this paper, we discuss arbitrary of Scaling and prove that the arbitrary of Scaling is reduced by making the difference of the power of separated signals and the power of observated signals into the minimum. We propose new algorithm that minimizes the difference of the power for BSS and show the effectiveness of our method by the computer simulation. |
