Abstract

UN SYSTÈME DE COMMUNICATION CELLULAIRE QUI UTILISE LE MULTIPLEXAGE PAR RÉPARTITION ORTHOGONALE DE LA FRÉQUENCE (MROF) DANS SON INTERFACE RADIO EST CAPABLE D'UTILISER SOIT UN PREMIER ESPACEMENT DE SOUS-PORTEUSE, SOIT UN SECOND ESPACEMENT DE SOUS-PORTEUSE. LA SOUS-PORTEUSE QUI EST UTILISÉE EST INDIQUÉE PAR PRODUCTION D'UN PREMIER TYPE DE SIGNAL DE SYNCHRONISATION LORSQUE C'EST LE PREMIER ESPACEMENT DE SOUS-PORTEUSE QUI EST UTILISÉ ET PAR PRODUCTION D'UN SECOND TYPE DE SIGNAL DE SYNCHRONISATION LORSQUE C'EST LE SECOND ESPACEMENT DE SOUS-PORTEUSE QUI EST UTILISÉ. QUEL QUE SOIT LE TYPE DE SIGNAL DE SYNCHRONISATION PRODUIT, IL EST TRANSMIS. POUR DISTINGUER LE PREMIER ET LE SECOND TYPE DE SIGNAL DE SYNCHRONISATION, UNE REPRÉSENTATION DANS LE DOMAINE TEMPOREL DU SECOND TYPE DE SIGNAL DE SYNCHRONISATION COMPREND UNE PLURALITÉ D'INSTANCES DU PREMIER TYPE DE SIGNAL DE SYNCHRONISATION.
