Abstract

Il est proposé un dispositif de réduction (10) de bruit dans un signal radio reçu dans la bande FM, comprenant : un module (11) de démodulation du signal radio, adapté pour générer un signal radio démodulé à partir du signal radio reçu, un module (12) de suppression de bruit adapté pour remplacer une séquence temporelle du signal radio démodulé par une séquence débruitée, un module (13) de commande du module de suppression de bruit, adapté pour contrôler l’activation du module de suppression de bruit, le dispositif de réduction de bruit étant caractérisé en ce qu’il comprend en outre un module (14) d’analyse du spectre fréquentiel du signal radio reçu, et en ce que le module de commande est configuré pour commander le module de suppression de bruit selon une stratégie d’activation choisie parmi plusieurs stratégies d’activation prédéterminées en fonction du contenu spectral du signal radio reçu.
