Title: 3 - Discrimination temporelle d'échos impulsifs qui se chevauchent
Author: CARBO FITE (R.); RANZ GUERRA (C.)
Abstract: Traitement d'un écho acoustique lorsque celui-ci est la somme d'impulsions identiques au signal émis, mais avec une amplitude et un retard différents
Description: This paper presents the processing of on acoustic echo built up by a sum of identical replicas of a given emitted signal; the sum terms have différent amplitude and phase . The method here presented consists in comparing, in a recurrent way, the envelope and the phase function of the echo with those of the emitted signal, and then getting the delays and amplitudes of the pulses that made up the echo.
