Abstract

Des signaux transmis via une pluralité de bandes de fréquences par un émetteur au moyen d'ensembles respectifs d'une ou de plusieurs chaînes d'émission sont reçus par un dispositif récepteur. Les signaux sont traités au niveau du récepteur au moyen d'une pluralité de chaînes de réception, y compris au moyen d'un ensemble de premières chaînes de réception associées à une première bande de fréquences et au moyen d'une ou de plusieurs deuxièmes chaînes de réception associées à la deuxième bande de fréquences. Un nombre de chaînes de réception dans le premier ensemble de chaînes de réception est différent d'un nombre de chaînes d'émission utilisées par le dispositif émetteur pour émettre via la première bande de fréquences. Un nombre de chaînes de réception dans le deuxième ensemble de chaînes de réception est différent d'un nombre de chaînes d'émission utilisées par le dispositif émetteur pour émettre via la deuxième bande de fréquences. Un traitement MIMO est réalisé sur les sorties de l'ensemble des premières chaînes de réception.
