Abstract

Selon l'invention, un système de transmission de données numérique décentralisé présente de nombreuses stations réparties, qui peuvent effectuer un échange de donnés uniquement avec des stations voisines. Les stations se trouvant entre une station source et une station cible font fonction de stations relais. La transmission d'une station à l'autre s'effectue à chaque fois sur des canaux différents. Dans chaque station est effectuée une conversion des signaux reçus par un canal de réception, sur un canal d'émission différent de ce dernier. La conversion d'un train de bits ou de symboles arrivant sur le canal de réception s'effectue symbole par symbole ou bit par bit, de sorte que les données sont transmises en flux continu, sans apparition de retards importants lors de la conversion, comme cela se produit lors de la transmission par paquets. Une matrice de couplage (KM) est utilisée pour la conversion. Chaque canal (C1...Cn) est divisé en une pluralité de canaux secondaires (CH-1...CH-8). L'affectation des canaux s'effectue de sorte que chaque station utilise, pour l'émission, si possible uniquement les canaux secondaires (SC1...SC8) situés dans le même canal.
