Abstract

L'invention concerne un récepteur sans fil capable d'estimer un canal haute précision et de générer un profil de retard, l'estimation du canal et la détection du profil de retard étant effectuées non seulement en fonction d'un canal physique individuel (DPCH) mais également en fonction d'un signal de canal commun, par exemple, un canal partagé de liaison descendante (DSCH).
