Title
(EN) APPARATUS AND METHOD FOR TRANSMITTING PREAMBLE IN BROADBAND WIRELESS COMMUNICATION SYSTEM
(FR) APPAREIL ET PROCÉDÉ PERMETTANT DE TRANSMETTRE UN PRÉAMBULE DANS UN SYSTÈME DE COMMUNICATION SANS FIL À LARGE BANDE
Abstract
(EN)
Preamble transmission in a broadband wireless communication system is provided. A method for transmitting a preamble includes determining a sequence as the preamble according to a transmit bandwidth, allocating sub-blocks of the sequence to a plurality of transmit antennas used to transmit the preamble, the number of the sub-blocks allocated to each antenna falling within two consecutive integers, and transmitting the preamble through the plurality of the transmit antennas according to the allocation result of the sub-blocks.

La présente invention se rapporte à une transmission de préambule dans un système de communication sans fil à large bande. Un procédé permettant de transmettre un préambule consiste à : déterminer une séquence en tant que préambule en fonction d'une largeur de bande de transmission; allouer des sous-blocs de la séquence à une pluralité d'antennes de transmission utilisées pour transmettre le préambule, le nombre de sous-blocs alloués à chaque antenne étant de deux nombres entiers consécutifs; et transmettre le préambule au moyen de la pluralité des antennes de transmission en fonction du résultat de l'allocation des sous-blocs.
