新CICA一单元ICA-R固定点算法
Fixed-point algorithm based on new CICA for one-unit ICA-R
摘要
Abstract
One-unit ICA-R is an efficient method utilizing prior information to extract an expected source signal.Aimed at flaw of the fast algorithm based on kurtosis,it performs theoretical analysis on the fast algorithm under two common close ness measurements, points out the reason of lower accurate extraction rate.lt proposes a fixed-point algorithm through remov ing invalidation of inequality constraints based on new CICA.Computer simulations verify that the fixed-point algorithm can converge faster and extract more accurately with almost same extraction performance of the fast algorithm.关键词
