Abstract

Système de communication à accès multiple par répartition dans le temps dans lequel les stations sont réparties en groupes, chaque groupe utilisant une paire de fréquences émission-réception différentes. La trame T est utilisée en périodes T 11 et T 12 variables. Les communications entre stations d'un même groupe sont établies pendant T 11 alors que les communications entre stations de groupes différents sont établies pendant T 12. Application aux systèmes de communication par satellite.
