Abstract(in Japanese) (See Japanese page)
Abstract(in English) This paper presents a method of blind separation which can separate original signals from their mixtures observed by the same number of sensors. The blind separation can be achieved without using strong assumption about source signals and any information about the mixing process, i. e., the transfer function between signal sources and sensors, except the fact that source signals are mutually statistically independent. Our proposed method can separate non-stationary signals (e. g., speech signal, music) from their mixtures. We apply our method to an experiment which extracts two source signals from their mixtures observed in a normal room.
