Abstract

L'invention concerne un procédé pour régler automatiquement une unité d'accord à accès d'entrée multiples et accès de sortie multiples. L'invention concerne aussi un émetteur-récepteur radio utilisant ce procédé. Un émetteur-récepteur radio selon l'invention comporte : 4 antennes (1 1) (12) (13) (14) qui forment un réseau d'antennes à accès multiples (1) ; une unité d'accord à accès d'entrée multiples et accès de sortie multiples (4) ayant 4 accès d'entrée et 4 accès de sortie ; 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 d'entrée, une et une seule des excitations étant appliquée à chacun des accès d'entrée, l'unité radio délivrant des instructions de réglage d'unité d'accord ; et une unité de contrôle (6), qui délivre un ou plusieurs signaux de contrôle d'accord à l'unité d'accord à accès d'entrée multiples et accès de sortie multiples.A method for automatically tuning a multi-input, multiple-output port tuning unit is provided. The invention also relates to a radio transceiver using this method. A radio transceiver according to the invention comprises: 4 antennas (1 1) (12) (13) (14) which form a network of multiple access antennas (1); a multiple input port and multiple output port tuning unit (4) having 4 input ports and 4 output ports; 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 authorization to use, for excitations intended for adjustment, one or more data symbols, the radio unit applying 4 excitations at the input ports, one and only one of the excitations being applied to each of the input ports, the radio unit providing tuning unit setting instructions; and a control unit (6), which outputs one or more tuning control signals to the multiple input port and multiple output port tuning unit.
