Title (EN) TIME DOMAIN INGRESS NOISE DETECTION AND CANCELLATION
(FR) DÉTECTION ET ANNULATION DE BRUIT D'ENTRÉE D'UN DOMAINE TEMPOREL
Abstract:
(EN) An apparatus, comprising a receiver configured to receive a primary signal that comprises a narrowband noise component and a broadband noise component, a processor coupled to the receiver and configured to determine, in a time domain, an estimate of the narrowband noise component in real-time, determine a cancelled output signal in real-time that comprises an estimate of the broadband noise component, and determine an estimate of a power level of the narrowband noise component in real-time.
(FR) L’invention concerne un appareil comprenant : un récepteur configuré pour recevoir un signal principal qui comprend une composante de bruit à bande étroite et une composante de bruit à large bande ; un processeur couplé au récepteur et configuré pour déterminer, dans un domaine temporel, une estimation de la composante de bruit à bande étroite en temps réel ; déterminer un signal de sortie annulé en temps réel qui comprend une estimation de la composante de bruit à large bande ; et déterminer une estimation d'un niveau de puissance de la composante de bruit à bande étroite en temps réel.
