Abstract

L'invention porte sur des techniques et des systèmes, qui, permettant de formaliser une planification des fréquences à spectre discontinu, maximisent les capacités du système tout en minimisant l'éventualité d'une survenue de brouillage dans le canal adjacent. Dans le contexte d'une plan d'ensemble des fréquences du système, il est possible de faire intervenir une séparation spatiale pour décaler le chevauchement résultant d'un mappage de découpage en canaux lorsque des fréquences supplémentaires font défaut. On peut alors utiliser une modification et/ou une définition site par site pour empêcher la survenue de produits d'intermodulation et/ou des brouillages dans le canal adjacent. Il faut alors prendre en considération un certain nombre de facteurs, au nombre desquels, notamment, la position du canal de commande de canal et la séparation dans un nouveau spectre, l'utilisation de blocs de probabilité, les seuils pour brouillage dans le canal adjacent, le brouillage dans le canal adjacent symétrique contre brouillage asymétrique, le type de plan de fréquence, les effets d'intermodulation, la topographie locale, les conditions d'environnement de fréquence et la disponibilité du site. Ces techniques se révèlent des plus utiles, mais sans se limiter à cet usage, s'agissant d'établir un système de communication radio cellulaire utilisant une bande de fréquence inférieure par superposition d'un découpage en canaux de 30 kHz sur des parties de bande de radio mobile spécialisé (SMR) à découpage de canaux de 25 kHz.
