Title (EN) METHOD AND APPARATUS FOR IMPROVING RECEPTION IN MULTIPLE ACCESS COMMUNICATION SYSTEMS
(FR) PROCEDE ET DISPOSITIF PERMETTANT D'AMELIORER LA RECEPTION DANS DES SYSTEMES DE COMMUNICATIONS A ACCES MULTIPLE
Abstract: front page image
(EN)An apparatus, system and method for improving the SNR of a desired signal received at a receiver in a multiple access communication system is disclosed. The apparatus, system and method subtracts known or knowable signals from the total signal received at the receiver and the desired signal is them determined from the result of the subtraction. The known, or knowable, signals can be synchronization signals or other interfering channel signals transmitted by the transmitter, such as a wireless network base station, serving the receiver, such as a subscriber station in such a wireless network, and/or can be such signals transmitted by another transmitter, such as an adjacent base station, or an adjacent sector in multi-sector systems.
(FR)L'invention concerne un appareil, un système et un procédé permettant d'améliorer le rapport signal/bruit d'un signal utile reçu par un récepteur dans un système de communications à accès multiple. On soustrait des signaux connus ou pouvant être connus, du signal total, puis le signal utile est déterminé à partir du résultat de la soustraction. Il peut s'agir de signaux de synchronisation ou autres signaux de canaux brouilleurs émanant d'un émetteur, du type station de base de réseau sans fil, à destination d'un récepteur, du type station d'abonné dans un réseau sans fil, et/ou de signaux émanant d'un autre émetteur, du type station de base adjacente, ou secteur adjacent dans des systèmes multisecteur.
