Publication number: 20140254825Abstract: Reducing feedback in an input signal that contains a signal component based on an output signal from a proximate output. The input signal is separated into a plurality of frequency bands by band pass filters. The power of signal in each band is determined, and the band signal with the greatest power is selected. That band's signal is sampled at a sampling rate, and at regular intervals one of the samples is selected. Blind signal separation is used to estimate signal sources from the selected samples. The estimated signals are compared to the output signal, and the estimated signal most similar to the output signal is subtracted from the input signal.Type: ApplicationFiled: March 7, 2014Publication date: September 11, 2014Applicant: BOARD OF TRUSTEES OF NORTHERN ILLINOIS UNIVERSITYInventor: Mansour Tahernezhadi
