Abstract

L'invention concerne un système d'élimination d'interférences sur bande étroite pour un récepteur à large bande DSSS par la pondération d'une copie multicanaux (56) du signal d'intérêt conformément au résultat de la corrélation entre une copie de bande étroite (66) du signal multicanaux d'intérêt centré sur la fréquence centre de l'interférence sur bande étroite et une copie de bande étroite (68) d'un signal de rétroaction centré sur la fréquence centre de l'interférence bande étroite. On injecte ensuite la copie pondérée sur bande étroite (106) du signal multicanaux dans un trajet de signal reçu pour éliminer l'interférence sur bande étroite.
