Title
(EN) A DATA RECEIVER HAVING MEANS FOR MINIMIZING INTERFERENCE AND METHOD USED IN SUCH A RECEIVER
(FR) RECEPTEUR DE DONNEES COMPORTANT DES MOYENS DE REDUCTION AU MINIMUM DES INTERFERENCES ET PROCEDE MIS EN OEUVRE DANS UN TEL RECEPTEUR
Abstract
(EN) The present invention relates to a data receiver (5) for receiving user data and reference data (CPICH) coming from a transmitter 5 via at least a channel. This receiver comprises means for unscrambling (39,66,64) and means for despreading (40,68) received data, means for analyzing the characteristic of the channel (35), means for evaluating the contribution of interference of data caused by the channel(IEP1Fj-IEPKFj) and a substracter means intended for cancelling the contribution of interference in the user data, said substracter means (62) being placed before said unscrambling means.
(FR) La présente invention se rapporte à un récepteur de données (5) adapté pour recevoir des données d'utilisateur et des données de référence (CPICH) en provenance d'un émetteur (5) par l'intermédiaire d'au moins un canal. Ce récepteur comporte des moyens de décryptage (39, 66, 64) et des moyens de désétalement (40, 68) des données reçues, des moyens d'analyse des caractéristiques du canal (35), des moyens d'évaluation de la contribution des interférences des données provoquées par le canal (IEP1Fj-IEPkFj) et des moyens de soustraction destinés à annuler la contribution des interférences dans les données d'utilisateur, ces moyens de soustraction (62) étant placés en amont desdits moyens de décryptage.
