A SIMPLE ECHO ATTENUATION IN SIGNALS

Pavel Zahradnik

Abstract


A simple yet powerful procedure for an echo attenuation in signals is introduced. The presented method involves no external reference signal. It is based on comb FIR filtering. To the advantages of the described method belong the simplicity and performance which are beneficial in real time implementations. For illustration, a simulation of the procedure is included. The efficiency of the presented method is demonstrated by a real time implementation on a digital signal processor.

Keywords


Echo attenuation, single-channel, autocorrelation, comb filter, real- time implementation, digital signal processor
