Abstract

Un système de communication par satellite est présenté comportant au moins un satellite dans lequel chaque satellite fournit plusieurs faisceaux, une pluralité d'UT et au moins une passerelle reliée à un PSTN et communiquant avec ladite au moins une UT ou avec une constellation, où chacune des UT à l'intérieur d'une bande de fréquences donnée est distinguée d'une autre des UT à l'aide d'une combinaison de multiplexage temporel et de codes de bruit non orthogonal pseudo-aléatoire et de créneaux temporels.
