Abstract

Système servant à réaliser des télécommunications en duplex à répartition dans le temps sur une seule bande de fréquence, ce qui permet de diminuer le dépassement du temps de protection par réglage actif de la synchronisation de la transmission à liaison inverse en fonction du temps de propagation aller-retour. En réaction à un message d'interrogation émis par la station de base, une station usager cherchant à établir une communication, émet un message de réponse. La station de base, au moyen d'un calculateur de temps de propagation (812), calcule la distance à laquelle se trouve la station usager par mesure du temps de propagation par rapport à la réception du message de réponse et en utilisant un ensemble de commande de synchronisation (806), ainsi qu'un émetteur (807), pour envoyer une instruction de réglage de synchronisation à la station usager, en lui donnant l'ordre d'avancer ou de retarder sa synchronisation. La station de base contrôle ensuite les émissions de la station usager et lui donne l'ordre périodiquement de régler sa synchronisation de façon similaire. La station usager émet un préambule de commande au départ de chaque tranche de temps, afin de permettre à la station de base d'effectuer des calculs de synchronisation aller-retour, ainsi que des réglages de la puissance ou de la sélection d'antenne de la station usager.
