CA 2516181

In a communication system, a method for estimating a transmitted signal is disclosed. A communication signal is received. A delay-power analyzer analyzes the communication signal. A delay spread is then estimated from information obtained from the delay-power analyzer. A new equalizer filter length is determined based on the estimated delay spread. An equalizer is configured to use the new equalizer filter length.

Dans un système de communication, une méthode de l'invention permet d'estimer un signal transmis. Un signal de communication est reçu. Un analyseur de puissance de temps de propagation analyse le signal de communication. Un défilement du temps de propagation est ensuite estimé à partir des informations obtenues à partir de l'analyseur de puissance de temps de propagation. Une nouvelle longueur de filtre d'égaliseur est déterminée en fonction du défilement du temps de propagation estimé. Un égaliseur est configuré pour utiliser la nouvelle longueur de filtre d'égaliseur.
