Abstract

L'invention porte sur des systèmes et sur des procédés pour une liaison terrestre sans fil dans un système à plusieurs antennes (MAS) avec des transmissions à de multiples utilisateurs (MU) (« MU-MAS »). Par exemple, un système à plusieurs antennes (MAS) et à multiples utilisateurs (MU) selon un mode de réalisation comporte : une ou plusieurs unités centralisées, couplées en communication à de multiples stations d'émission-réception distribuées par l'intermédiaire d'un réseau ; le réseau est constitué de liaisons filaires ou sans fil ou d'une combinaison des deux, employées en tant que canal de communication de liaison terrestre ; l'unité centralisée transforme les N flux d'informations en M flux de bits, chaque flux de bits étant une combinaison de certains ou de la totalité des N flux d'informations ; les M flux de bits sont envoyés sur le réseau aux stations d'émission-réception distribuées ; les stations d'émission-réception distribuées envoient simultanément les flux de bits sur des liaisons sans fil à au moins un dispositif client de manière que le ou les dispositifs clients reçoivent au moins un des N flux d'informations originaux.
