The invention relates to a method for estimating a carrier leak making it possible to solve the accuracy degradation problem associated to a poor reception by a central carrier. The aim of said invention is the method for estimating a carrier leak consisting in applying a complex gain variation Z to a received signal s between at least two predetermined values Z1 and Z2, measuring the position (PD1, PD2) of the central carrier of the signal s demodulated for each applied gain (Z1, Z2) and in calculating at least one part of the carrier leak on the base of the measured positions (PD1, PD2) and of the applied gain (Z1, Z2), said calculated carrier leak part (offset-mod) corresponding to a leak due to a modulator.

L'invention concerne une méthode d'estimation du résidu de la porteuse. Elle permet de répondre au problème de dégradation de la précision qui est liée à une mauvaise réjection de la porteuse centrale. Un objet de l'invention est une méthode d'estimation de résidu de la 5 porteuse comportant : - La variation d'un gain complexe Z appliqué au signal reçu s entre au moins deux valeurs prédéterminées Zl et Z2 ; - La mesure de la position (PD1, PD2) de la porteuse centrale du signal s démodulé pour chacun des gains (Zl, Z2) appliqués ; - Le calcul d'au moins une partie du résidu de la porteuse à partir des positions mesurées PDl et PD2 et des gains appliquées Zl et Z2, la partie du résidu de la porteuse calculée (offset-mod) correspondant au résidu dû au modulateur.
