Abstract

L'invention concerne un appareil caractérisé en ce qu'une unité (26) de calcul de courbes de régression qui détecte une différence de phase entre des données qui ont été codées avec correction d'erreurs sur la base de données décodées qui ont été décodées de façon répétée par une unité (25) de décodage somme-produit et des données après décodage, réduit les variations de la composante de différence de phase par filtrage en utilisant une approximation d'une courbe de régression et détecte des valeurs estimées d'une erreur de déphasage et une quantité dé variation de phase par rapport à la composante de différence de phase après filtrage. Une unité (27) de calcul d'erreur de phase, sur la base de l'erreur de déphasage et de la quantité dé variation de phase, effectue une correction d'erreur de phase pour les données codées avec correction d'erreurs. L'unité (25) de décodage somme-produit effectue de façon répétée un décodage sur une valeur obtenue en effectuant une correction d'erreur de phase sur les données codées avec correction d'erreurs.
