Abstract

Un système et un procédé permettant de compenser les décalages de fréquence et de phase dans un système dantenne multiple (MAS) avec des transmissions multi-utilisateurs (MU) (« MU-MAS ») sont décrits. Le procédé peut comprendre la transmission dun signal dentraînement à partir de chaque antenne dune station de base à lune dune pluralité de dispositifs client sans fil, la génération de données de compensation de décalage de fréquence, la réception des données de compensation de décalage de fréquence au niveau de la station de base, le calcul de poids de précodeur MU-MAS en se basant sur les données de compensation de décalage de fréquence pour préannuler le décalage de fréquence au niveau de lémetteur, et le calcul dune pluralité de poids de précodeur MU-MAS en se basant sur des données de caractérisation de canal.
