Abstract
(EN)
There are included a receiving part (4) that receives frequency multiplexed signals in which carrier groups have been multiplexed; a first demodulating means (5) that outputs a first data carrier and a first transmission control carrier; a second demodulating means (6) that outputs a second data carrier and a second transmission control carrier; a timing adjusting part (7) that synchronizes the processing timings of the first and second demodulating means (5,6); a first combining/selecting part (60) that combines or selects the first and/or second transmission control carrier(s); a second combining/selecting part (8) that combines or selects the first and/or second data carrier(s); a decoding part (13) that uses the transmission control carrier selected by the first combining/selecting part (60) to decode a transmission control signal; and a detecting part (14) that detects a frame synchronization.

La présente invention concerne une partie de réception (4) qui reçoit des signaux à multiplexage de fréquence dans lesquels des groupes de porteuses ont été multiplexés. L'invention vise également : un premier moyen de démodulation (5) qui extrait une première porteuse de données et une première porteuse de commande de transmission ; un second moyen de démodulation (6) qui extrait une seconde porteuse de données et une seconde porteuse de commande de transmission ; une partie d'ajustement de synchronisation (7) qui synchronise les synchronisations de traitement du premier et du second moyen de démodulation (5,6) ; une première partie de sélection/combinaison (60) qui combine ou choisit la première et/ou la seconde porteuse de commande de transmission ; une seconde partie de sélection/combinaison (8) qui combine ou choisit la première et/ou seconde porteuse de données; une partie de décodage (13) qui utilise la porteuse de commande de transmission choisit par la première partie de sélection/combinaison (60) pour décoder un signal de commande de transmission ; et une partie de détection (14) qui détecte une synchronisation de trame.
