Abstract

Procédé de réduction d'interférence multi-trajets, pour un récepteur radio de véhicule comprenant au moins deux antennes de réception radio (A1, A2) recevant chacune une pluralité de signaux radio (X1,n, X2,n) composés de signaux radio décalés temporellement, issus d'un phénomène de multi-trajets, lesdites pluralités de signaux radio étant combinées pour fournir un signal radio combiné yn à restituer, avec : à l'instant n, où X1, respectivement X2 est un vecteur dont les composantes correspondent à la pluralité de signaux reçus par la première antenne (A1), respectivement la deuxième antenne (A2), et sont des scalaires dont les composantes sont des poids complexes d'un filtre spatial et est la matrice transposée d'un vecteur dont les composantes sont des poids complexes d'un filtre temporel, ledit procédé comprenant la mise en œuvre d'un algorithme d'adaptation itératif pour déterminer lesdits poids complexes du filtre spatial et lesdits poids complexes du filtre temporel.
