(FR) PROCÉDÉS ET SYSTÈMES AVEC UNE CLASSIFICATION D'ÉTALEMENT DOPPLER SIMPLIFIÉE
Abstract: front page image
(EN)The frequency offset of a received signal in a WiMAX system is estimated by a frequency-tracking loop discriminator. Then a Doppler spread of the wireless channel is estimated based on the frequency offset, and classified based on comparison with threshold values.
(FR)Le décalage de fréquence d'un signal reçu dans un système WiMAX est estimé par un discriminateur à boucle de suivi de fréquence. Ensuite, un étalement Doppler du canal sans fil est estimé sur la base du décalage de fréquence, et classé sur la base d'une comparaison avec des valeurs seuils.
