Abstract

A signal processing system for generating a signal component reduced output signal by estimating the power spectrum of a non-stationary signal component within a non-stationary input signal is disclosed. The estimated power spectrum of the signal component is determined by using a gamma delay line (GDL) filter. The weights of the GDL filter are adaptively updated in accordance with a detection method that is designed to detect the presence of the non-stationary signal component. By subtracting the estimated power spectrum of the signal component from the power spectrum of the entire input signal, a signal component reduced output signal can be generated.
