A method of controlling sampling frequency of a sampling device (40), where the sampling device (40) generates samples (62) in response to the receipt of a signal (20) resulting from a transmission of a series of symbols through a channel, the method including the steps of estimating (46) a channel impulse response of the channel from the samples, calculating a characteristic of the channel impulse response estimate, and determining (52) the sampling frequency in accordance with the characteristic.
La présente invention concerne un procédé de réglage de la fréquence d'échantillonnage d'un échantillonneur (40) générant des échantillons (62) en réaction à la réception d'un signal (20) résultant de l'émission d'une série de symboles via un canal. Ce procédé comporte plusieurs opérations. On commence par évaluer (46) une réponse d'impulsion canal du canal à partir des échantillons. On calcule ensuite la caractéristique de l'évaluation de la réponse d'impulsion canal. Enfin, on détermine (52) la fréquence d'échantillonnage en fonction de la caractéristique.
