Abstract

Un système permêt de minimiser les brouillages co-canal survenant à la périphérie commune de secteurs d'émission. Ce système permet d'exploiter la séparation géographique d'émetteurs (12) mobiles éventuellement brouilleurs et d'utiliser la maîtrise de la puissance d'émission. Il comporte des antennes sectorielles dans un système AMRT et à sauts de fréquences combiné où chaque utilisateur d'un secteur donné reçoit un créneau temporel propre au système inventé en fonction de sa position géographique dans ce secteur. La puissance d'émission dans ce secteur est réduite pendant certains crénaux temporels pré-déterminés qui sont attribués aux utilisateurs éloignés des bords dudit secteur. Sur la liaison montante, la puissance d'émission destinée aux utilisateurs proches du bord est réduite pour provoquer moins de brouillage co-canal entre leurs signaux et ceux d'autres utilisateurs utilisant le même créneau temporel dans d'autres secteurs.
