SIGNAL PROCESSOR FOR REDUCING UNDESIRABLE SIGNAL CONTENT

摘要

A signal processor for reducing undesirable signal content reduces the undesirab le signal content by exaggerating the undesirable signal content and then using thi s exaggerated undesirable signal and adaptive filter means to estimate the undesirable content in the signal and then substantially removing it from the signal. The signal processor include s a signal mapping means for exaggerating the undesirable signal content; and an adaptive f ilter means for reducing the undesirable signal content using the exaggerated undesirable si gnal content.
