Abstract

L'invention concerne des procédés et un appareil pour synchroniser un récepteur sans fil avec un émetteur comprenant des procédés et un appareil pour calculer un décalage fractionnel de fréquence porteuse (FCFO). Le récepteur sans fil reçoit un signal qui contient un symbole de multiplexage par répartition orthogonale de la fréquence (OFDM)/ d'accès multiple par répartition orthogonale de la fréquence (OFDMA) qui correspond à un canal de synchronisation primaire (P-SCH) codé ou modulé selon une séquence d'autocorrélation d'amplitude zéro constante (CAZAC). Le récepteur sans fil génère une valeur FCFO estimée par calcul d'une phase différentielle d'une corrélation croisée entre une première moitié du symbole OFDM/OFDMA de domaine temporel reçu et une seconde moitié du symbole OFDM/OFDMA de domaine temporel reçu.
