Abstract

L'invention concerne un procédé de détection de vitesse dans un système de communication, un récepteur, un élément de réseau, et un processeur, le processeur comprenant, par exemple, des moyens de détermination d'un nombre prédéterminé d'estimations de fréquence, des moyens de détermination d'une moyenne des estimations de fréquence en vue d'obtenir un décalage de fréquence moyenne (300), des moyens d'estimation exact des échantillons reçus et/ou des valeurs de réponse d'impulsions utilisant le décalage de fréquence moyenne (300), des moyens permettant de calculer les estimations de fréquence Doppler en utilisant les échantillons reçus exempts d'erreurs systématiques et/ou des valeurs de réponse d'impulsions (302), ainsi que des moyens de calcul des statistiques de second ordre sélectionné des estimations de fréquence Doppler sur une période prédéterminée (304).
