The present invention relates to a method for acquiring a configuration of a re-configurable antenna (A), having at least two different antenna element configurations, where the antenna's element mutual coupling characteristics are known in advance in the form of an antenna coupling matrix (Ck(n)), the acquired configuration having a desired effect on a transmission channel, the method comprising the steps: setting (8) an initial configuration of the re- configurable antenna, resulting in an initial coupling matrix (C0); estimating (9) the transmission channel matrix (H(n)), which transmission channel matrix (H(n)) includes the effect of the antenna; calculating (10) a generic transmission channel matrix (H(n)), which generic transmission channel matrix (H(n)) excludes the effect of the antenna; and extracting (11 ) a coupling matrix (C) that provides a desired transmission channel matrix (H(n)), including the effect of the antenna.
L'invention concerne un procédé d'acquisition d'une configuration d'une antenne reconfigurable (A), possédant au moins deux configurations d'éléments d'antenne différentes, les caractéristiques de couplage mutuel des éléments de l'antenne étant connues d'avance sous la forme d'une matrice de couplage d'antenne (Ck(n)), la configuration acquise ayant un effet souhaité sur un canal de transmission, le procédé comprenant les étapes consistant à : fixer (8) une configuration initiale de l'antenne reconfigurable pour produire une matrice de couplage initiale (C0); estimer (9) une matrice de canaux de transmission (H(n)), ladite matrice de canaux de transmission (H(n)) incorporant l'effet de l'antenne; calculer (10) une matrice de canaux de transmission générique (H(n)), ladite matrice de canaux de transmission générique (H(n)) excluant l'effet de l'antenne; et extraire (11) une matrice de couplage (C) produisant une matrice de canaux de transmission recherchée (H(n)), incorporant l'effet de l'antenne.
