Abstract
La présente invention concerne un dispositif de communication sans fil MIMO comprenant, en partie, un premier chemin de transmission conçu pour transmettre un premier signal de transmission à partir d'une première antenne, un deuxième chemin de transmission conçu pour transmettre un deuxième signal de transmission à partir d'une deuxième antenne, un premier chemin de réception étant conçu pour recevoir un premier signal de réception, un circuit d'annulation d'interférences et un contrôleur. Le circuit d'annulation comporte une structure de filtres en cascade, chaque filtre comportant une multitude de prises de bascule comprenant chacune un élément variable. Le contrôleur varie dynamiquement une valeur appliquée à chacun de la pluralité d'éléments variables selon des caractéristiques de réponse de fréquence de l'élément variable pour supprimer une partie d'un signal d'auto-interférences et/ou de diaphonie présent dans un signal reçu par le dispositif.
