Abstract

L'invention concerne un procédé et un système permettant de simplifier le traitement des signaux entre l'ensemble formant cornet d'alimentation et les systèmes de relais de trames. Les données sont directement modulées à partir des systèmes de relais de trames sur un support de bandes L et converties à une fréquence supérieure en vue de leur sortie au niveau du cornet d'alimentation. Cette conversion est facilitée par l'addition d'un signal de puissance en courant continu et d'un signal de référence d'une fréquence de 10,0 MHz au signal modulé de la bande L (de manière à protéger la référence de fréquences contre toute variation due aux éléments externes) tout en conservant la pureté spectrale du signal modulé de la bande L.
