ACTIVE NOISE REMOVAL METHOD USING INDEPENDENT COMPONENT ANALYSIS

摘要

PROBLEM TO BE SOLVED: To provide an active noise removal method using an independent component analysis which makes it possible to obtain noise removal performance more improved than the conventional LMS adaptive algorithm.;SOLUTION: Learning is carried out in such a manner that output signals are made independent from each other by taking secondary or higher order statistical characteristics into consideration, by which the independent component analysis method enabling signal separation is applied to an active noise remover.;COPYRIGHT: (C)2002,JPO
