Abstract
La présente invention concerne un procédé de communication à travers un réseau à accès multiple en phase aléatoire. Un signal qui a été étalé au moyen dun code de pseudo-bruit et déphasé par un déphasage aléatoire temporel et contenant une information de données utiles est reçu en provenance dun dispositif. Une destination est choisie pour linformation de données utiles en fonction dune caractéristique du réseau à accès multiple. Linformation de données utiles est transmise à la destination choisie.
