A method of controlling a feedforward filter of an equalizer includes the steps of generating a complex representation of an output of the feedforward filter and generating a representation of a decision from an output of the equalizer. The complex representation and the decision representation are correlated to obtain a phase error estimate. A phase correction value is generated based on the phase error estimate and used to adjust the phase of the output of the feedforward filter.

Un procédé de surveillance d'un filtre à action directe d'un correcteur de phase consistant à générer une représentation complexe d'une sortie du filtre et à générer une représentation d'une décision provenant de la sortie du correcteur de phase. La représentation complexe et la représentation de décision sont en corrélation afin d'obtenir une estimation d'erreur de phase. La valeur de correction de phase est générée d'après l'estimation d'erreur de phase et utilisée pour régler la phase de sortie du filtre.
