Title (EN) SYSTEM AND METHOD FOR NOISE SUPPRESSION IN A COMMUNICATION SIGNAL
(FR) SYSTEME ET PROCEDE DE SUPPRESSION DU BRUIT DANS UN SIGNAL DE COMMUNICATION
Abstract: front page image
(EN)A system and method for suppressing disturbance signal components in a communication signal is disclosed. The system and method utilize a priori information about the fundamental frequency of the disturbance signal component to generate an estimate of the disturbance signal component. This estimated disturbance signal may be subtracted from the communication signal to suppress the disturbance signal component in the communication signal.
(FR)L'invention concerne un système et un procédé de suppression des composants de signaux perturbateurs dans un signal de communication. Lesdits système et procédé utilisent une information a priori concernant la fréquence fondamentale du composant du signal perturbateur pour générer une estimation de ce composant. Ce signal perturbateur estimé peut être soustrait du signal de communication afin de supprimer le composant du signal perturbateur dans le signal de communication.
