Abstract

L'invention concerne un procédé pour régler automatiquement une pluralité d'antennes passives accordables d'un émetteur-récepteur radio qui communique dans un réseau radio en utilisant ces antennes passives accordables. L'invention concerne aussi un émetteur-récepteur radio utilisant ce procédé. Un émetteur-récepteur radio selon l'invention comporte : 4 antennes passives accordables (11) (12) (13) (14), chacune des antennes passives accordables étant une partie d'un réseau d'antennes à accès multiples (1) ayant 4 accès utilisateur ; 4 unités de détection (31) (32) (33) (34) ; 4 liaisons d'antenne (21) (22) (23) (24) ; une unité radio (8), l'unité radio recevant, d'un réseau radio, un signal radio procurant une autorisation d'utiliser, pour des excitations destinées à un réglage, un ou plusieurs symboles de donnée, l'unité radio appliquant 4 excitations aux accès utilisateur, une et une seule des excitations étant appliquée à chacun des accès utilisateur, l'unité radio délivrant des instructions de réglage d'antenne ; et une unité de contrôle (6), qui délivre un ou plusieurs signaux de contrôle d'antenne aux antennes passives accordables.A method is provided for automatically tuning a plurality of tunable passive antennas of a radio transceiver that communicates in a radio network using these tunable passive antennas. The invention also relates to a radio transceiver using this method. A radio transceiver according to the invention comprises: 4 tunable passive antennas (11) (12) (13) (14), each of the tunable passive antennas being part of an array of multiple access antennas (1) having 4 user access; 4 detection units (31) (32) (33) (34); 4 antenna links (21) (22) (23) (24); a radio unit (8), the radio unit receiving, from a radio network, a radio signal providing an authorization to use, for excitations intended for adjustment, one or more data symbols, the radio unit applying 4 excitations at user accesses, one and only one of the excitations being applied to each of the user accesses, the radio unit issuing antenna adjustment instructions; and a control unit (6), which delivers one or more antenna control signals to the tunable passive antennas.
