Title (EN) METHOD AND SYSTEM FOR ADAPTIVE PREFILTERING OF A SIGNAL FOR TRANSMISSION
(FR) PROCEDE ET SYSTEME DE PREFILTRAGE ADAPTATIF D'UN SIGNAL DE TRANSMISSION
Abstract: front page image
(EN)A method and system for adaptive prefiltering of a signal for transmission is described. The method includes determining a reference starting value of coefficients for a receiver equalizer filter, receiving an indication of a change in channel characteristics based on a signal received at the receiver equalizer filter, computing coefficients for an adaptive filter based on the reference starting value and the change in channel characteristics, setting the coefficients of the adaptive filter equal to the computed coefficients, and filtering a signal for transmission through the adaptive filter.
(FR)L'invention concerne un procédé et un système de préfiltrage adaptatif d'un signal de transmission. Le procédé consiste à déterminer une valeur de référence de départ des coefficients d'un filtre d'égalisation de réception, à recevoir une indication de changement des caractéristiques de canal en fonction d'un signal reçu au niveau du filtre d'égalisation de réception, à calculer les coefficients d'un filtre adaptatif à partir de la valeur de référence de départ et du changement des caractéristiques de canal, à déterminer les coefficients du filtre adaptatif égaux aux coefficients calculés, et à filtrer un signal de transmission au moyen du filtre adaptatif.
