摘要
Abstract
Blind signal separation(BSS)is applied to electromagnetic signals in order to remove the power line interference. Unified mod-el of BSS and ICA is established. Objective functions and arithmetics of fast ICA and maximum signal-noise-ratio ICA are analyzed. Different vaveform signals produced by computer and signals received by magnetic antenna are both separated by the two arithmetics. The result is that maximum signal-noise-ratio ICA is superior to fast ICA from similar coefficient and operation time.关键词
