CA 2302299

An adaptive antenna transmitter receiver chain (100) comprises a "dummy" interference addition unit (122) for generating far field radiation patterns which are added to the far field radiation pattern of an interfering signal. The resultant pattern is processed by a beamforming unit so as to calculate a set of antenna weights corresponding to a far field radiation pattern having a plurality of null points convergent upon a region of the far field radiation pattern.

L'invention porte sur une chaîne (100) d'émetteurs et de récepteurs à antennes adaptatives comprenant une unité d'addition (122) d'interférences fictives et permettant de générer des structures de rayonnements en champ lointain qui sont ajoutés à la structure de rayonnement en champ lointain d'un signal d'interférence. La structure obtenue est traitée par une unité de formation de faisceaux de façon à calculer un ensemble de poids d'antennes correspondant à une structure de rayonnement en champ lointain où une pluralité de points zéro convergent sur une seule région.
