Title (EN) COMMUNICATIONS SYSTEMS INCLUDING ADAPTIVE ANTENNA SYSTEMS AND METHODS FOR INTER-SYSTEM AND INTRA-SYSTEM INTERFERENCE REDUCTION
(FR) SYSTEMES DE COMMUNICATIONS COMPRENANT DES SYSTEMES D'ANTENNES ADAPTATIVES ET PROCEDES DE REDUCTION DE BROUILLAGE INTER-SYSTEMES ET INTRA-SYSTEMES
Abstract:
(EN) Methods of forming a downlink beam in an adaptive antenna system of a communications system that may reduce inter-system and/or intra-system interference include receiving vectors of signals including signals transmitted by user terminals of the communications system and signals transmitted by transceivers of an independent communications system, obtaining spatial information for the user terminals of the communications system and the transceivers of the independent communications system, generating complex transmitting weights that form spatial nulls directed at the transceivers of the independent communications system, and transmitting a downlink communications signal using the complex transmitting weights. Related systems are also disclosed.
(FR) L'invention concerne des procédés de formation d'un faisceau de liaison descendante dans un système d'antennes adaptatives d'un système de communications permettant de réduire le brouillage inter-systèmes et/ou intra-systèmes. Ces procédés consistent à recevoir des vecteurs de signaux comprenant des signaux transmis par des terminaux utilisateur du système de communications et des signaux transmis par des émetteurs-récepteurs d'un système de communications indépendant ; à obtenir des informations spatiales pour les terminaux utilisateur du système de communications et les émetteurs-récepteurs du système de communications indépendant ; à générer des pondérations de transmission complexes qui forment des 'blancs' spatiaux dirigés vers les émetteurs-récepteurs du système de communications indépendant ; et à transmettre un signal de communications de liaison descendante au moyen des pondérations de transmission complexes. L'invention concerne également des systèmes associés.
