Abstract

L'invention concerne un procédé d'estimation de voie dans des systèmes de radiotéléphonie mobile TDMA, consistant à utiliser, pour l'estimation d'une seule réponse d'impulsion de voie, les valeurs de réception de plusieurs paquets utilisables pour l'estimation de voie, dans le cas où l'intervalle de temps Tauf, dans lequel des paquets de données successifs sont transmis est sensiblement inférieur au temps cohérent TK.
