Abstract

L'INVENTION CONCERNE UN PROCÉDÉ, UN APPAREIL ET UN PROGRAMME INFORMATIQUE PERMETTANT D'AMÉLIORER LE RAPPORT SIGNAL-BRUIT D'UN SIGNAL S(T), S(T) REPRÉSENTANT LE SIGNAL ET LE BRUIT. UNE MESURE DE S(T) À UNE FRÉQUENCE D'INTÉRÊT EST OBTENUE. LES MESURES DE BRUIT DE S(T) À UNE OU PLUSIEURS FRÉQUENCES DE BRUIT AUXQUELLES LA PARTIE SIGNAL DE S(T) PRÉVUE EST RÉDUITE SONT OBTENUES. LE BRUIT À LA FRÉQUENCE D'INTÉRÊT EST ESTIMÉ À L'AIDE DES MESURES DE BRUIT AUXDITES FRÉQUENCES DE BRUIT. LE BRUIT ESTIMÉ EST SOUSTRAIT DE LA MESURE DE S(T) À LA FRÉQUENCE D'INTÉRÊT.
