Title:
ACTIVE NOISE REMOVAL METHOD USING INDEPENDENT COMPONENT ANALYSIS
Document Type and Number:
Japanese Patent JP2002189476
Kind Code:
A
Abstract:
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.
