Si les processus de télémétrie ne sont pas fréquents dans un système OFDMA de liaison montante, la synchronisation temporelle entre la station de base et les stations mobiles peut ne pas être maintenue et les performances peuvent être dégradées. Cet article propose un schéma d'accès aléatoire dans lequel un court symbole OFDMA est transmis pour maintenir l'orthogonalité avec des décalages temporels. Un symbole court est construit en insérant un remplissage de zéros dans un symbole OFDMA.

Abstract: If ranging processes are not frequent in an uplink OFDMA system, timing synchronization between the base and mobile stations may not be maintained and the performance may be degraded. This paper proposes a random access scheme in which a short OFDMA symbol is transmitted to maintain the orthogonality with timing offsets. A short symbol is constructed by inserting zero-padding to an OFDMA symbol.

AB - If ranging processes are not frequent in an uplink OFDMA system, timing synchronization between the base and mobile stations may not be maintained and the performance may be degraded. This paper proposes a random access scheme in which a short OFDMA symbol is transmitted to maintain the orthogonality with timing offsets. A short symbol is constructed by inserting zero-padding to an OFDMA symbol.
