CA 2516203

In a wireless communication system, a method for estimating a transmitted signal is disclosed. A wireless signal is received that includes a pilot channel and at least one other channel. A transmitted signal is estimated using an equalizer and the received wireless signal. Taps of a filter of the equalizer are adapted through use of a channel estimate. The channel estimate is calculated from the pilot channel. The pilot channel and the at least one other channel are separated.

La présente invention a trait à un système de communications sans fil dans lequel est mis en oeuvre un procédé d'estimation d'un signal transmis. Un signal sans fil est reçu comprenant une voie pilote et au moins une autre voie. Un signal transmis est estimé au moyen d'un égaliseur et du signal sans fil reçu. Des branchements de filtre de l'égaliseur sont adaptés par l'utilisation d'une estimation de voie. L'estimation de voie est calculée à partir de la voie pilote. La voie pilote et au moins une autre voie sont séparées.
