Patent

CA 2246865

A nonlinear processor (NLP) for selectively removing or reducing residual echo signals from an acoustic echo canceller associated with a telephony terminal is provided. Low level background noise and near end speech signals pass through the NLP structure substantially unaltered. Distortion, background noise above a preset threshold and echo signals including long duration echoes are replaced with a linear combination of previous noise data.

Processeur non linéaire (NLP) permettant de supprimer ou de réduire les signaux d'écho résiduel d'un suppresseur d'écho acoustique associé à un poste téléphonique. Les faibles bruits de fond et distorsions locales traversent la structure du NLP sans modification importante. La distorsion, le bruit de fond supérieur à un seuil préétabli et les signaux d'écho comprenant les échos de longue durée sont remplacés par une combinaison linéaire des données auparavant bruitées.
