Abstract
(EN)
A method of a communication receiver is disclosed. The method comprises receiving a signal comprising respective signal parts from a plurality of users, grouping the plurality of users into two or more groups, selecting a first one of the two or more groups, and processing the received signal to extract information of the respective signal part of each user of the first group, wherein the processing for the users of the first group is performed in parallel. The method also comprises regenerating the respective signal part of each user of the first group based on the corresponding extracted information, and removing the regenerated respective signal part of each user of the first group from the received signal to provide a first reduced received signal. Corresponding apparatus, communication receiver and computer program product are also disclosed.

L'invention concerne un procédé implémenté dans un récepteur de communication. Le procédé consiste à : recevoir, d'une pluralité d'utilisateurs, un signal contenant des parties de signal respectives ; grouper la pluralité d'utilisateurs en deux groupes ou plus ; sélectionner un premier des deux groupes ou plus ; et traiter le signal reçu de sorte à extraire des informations de la partie de signal respective de chaque utilisateur du premier groupe, le traitement pour les utilisateurs du premier groupe étant exécuté en parallèle. Le procédé consiste également à : régénérer la partie de signal respective de chaque utilisateur du premier groupe sur la base des informations extraites correspondantes ; et supprimer la partie de signal respective régénérée de chaque utilisateur du premier groupe à partir du signal reçu, afin de fournir un premier signal reçu réduit. L'invention concerne également un appareil, un récepteur de communication, et un produit programme d'ordinateur.
