The invention concerns a method for sampling a transmission channel affected by a time dispersion d from a training sequence (TS) and a reception signal (s) corresponding to said sequence, using a measuring matrix (M) elaborated from the training sequence (TS) taking into account the time dispersion. The method comprises a step which consists in producing dynamic pulse response of said channel according to the least squares technique as the combination of the static response (r) with (d+1) components and a time interval error (r').
L'invention concerne un procédé de sondage d'un canal de transmission affecté d'une dispersion temporelle (d) à partir d'une séquence d'apprentissage (TS) et d'un signal de réception (s) correspondant à cette séquence, ceci au moyen d'une matrice de mesure (M) établie à partir de la séquence d'apprentissage (TS) compte tenu de la dispersion temporelle. Le procédé comprend une étape pour produire la réponse impulsionnelle dynamique de ce canal selon la technique des moindres carrés comme la combinaison d'une réponse statique (r) à (d+1) composantes et d'une dérive temporelle (r').
