Title (EN) METHOD FOR CANCELLING MULTI-PATH SIGNALS FOR FREQUENCY-MODULATED RADIO SIGNAL RECEIVER
(FR) PROCÉDÉ DE SUPPRESSION DE SIGNAUX MULTI-TRAJETS POUR RÉCEPTEUR DE SIGNAUX RADIO MODULÉS EN FRÉQUENCE
Abstract:
(EN) Method for reducing multi-path interference to be implemented in a vehicle radio receiver comprising a radio-receiving antenna receiving a plurality of radio signals corresponding to a transmitted radio signal, said plurality of signals received by the antenna being composed of time-shifted radio signals, the plurality of signals being intended to be combined to provide a combined radio signal z n to be rendered, with z n = w T n Y n , the method being intended to determine the complex components of the complex weight vector and comprising: • introducing a temporal correlation between the real and imaginary portions of the complex weights, based on the time shift between the received signals, by means of the expression of the complex weights in polar coordinates, • the implementation of an iterative adaptation algorithm to determine the gains and delays of the complex weights, capable of maintaining a constant modulus of z n over time.
(FR) Procédé de réduction d'interférence multi-trajets, pour sa mise en œuvre dans un récepteur radio de véhicule comprenant une antenne de réception radio recevant une pluralité de signaux radio correspondant à un signal radio émis, ladite pluralité de signaux reçus par ladite antenne étant composés de signaux radio décalés temporellement, ladite pluralité de signaux étant destinés à être combinés pour fournir un signal radio combiné zn à restituer, avec zn = wTnYn, ledit procédé visant à déterminer lesdites composantes complexes dudit vecteur de poids complexes et comprenant : • l'introduction d'une corrélation temporelle entre les parties réelles et imaginaires desdits poids complexes, fonction du décalage temporel entre lesdits signaux reçus, au moyen de l'expression desdits poids complexes en coordonnées polaires, • la mise en œuvre d'un algorithme d'adaptation itératif pour déterminer les gains et retards desdits poids complexes, aptes à maintenir constant dans le temps le module de zn.
