The invention concerns a process for calibrating receiver and/or transmitter chains piloting a radiator antenna network, the said network being included in a spatial distribution multiple access (SDMA) cellular digital radio base station and making it possible to dynamically create receive and/or transmit beams directed at mobile stations in the so-called current cell associated with the said base station. With this invention, at least one of the mobile stations present in the current cell is a calibration sensor that, in addition to its regular function, receives and/or transmits at least one test signal to enable the calibration of the said receiver and/or transmitter chains.
L'invention concerne un procédé de calibrage de chaînes de réception et/ou d'émission pilotant un réseau d'antennes actives, ledit réseau d'antennes actives étant compris dans une station de base d'un système de radiocommunication numérique cellulaire du type à accès multiple à répartition spatiale (SDMA), et permettant de créer dynamiquement des faisceaux de réception et/ou d'émission en direction de stations mobiles présentes dans la cellule, dite cellule courante, associée à ladite station de base. Selon l'invention, au moins une des stations mobiles présentes dans la cellule courante, dite station-sonde de calibrage, est utilisée, outre sa fonction classique, comme sonde de calibrage, de façon à recevoir et/ou émettre au moins un signal de test permettant ledit calibrage desdites chaînes de réception et/ou d'émission.
