Abstract

L'invention concerne un procédé de détermination de positions d'émetteurs mobiles dans un système de communication sans fil, qui permet le calcul d'une signature à partie de signaux reçus au niveau d'un réseau d'antennes, provenant du mobile, et met la signature en correspondance avec des signatures étalonnées, mémorisées dans une base de données, de sorte que la position du mobile soit estimée. La signature contient des informations caractérisant le canal spatial entre le mobile et le réseau d'antennes. Un appareil (112) permettant la mise en oeuvre du procédé comprend un réseau d'antennes (116) et un récepteur multivoie (118) permettant la réception cohérente de vecteurs de signaux multidimensionnels en provenance d'un émetteur mobile. Un processeur (120) calcule une signature de signal à partir des vecteurs de signaux reçus, comparée à des signatures étalonnées, rangées dans une mémoire (122) pour l'identification de signatures étalonnées qui sont similaires à la signature calculée, et correspondant aux positions probables de l'émetteur mobile. Ainsi, la position de l'émetteur peut être déterminée avec précision à partir de signaux reçus au niveau d'une seule station de base, même dans un environnement à plusieurs trajets.
