Title (EN) POSITION ESTIMATION APPARATUS
(FR) APPAREIL D’ESTIMATION DE POSITION
Abstract:
(EN) A position estimation apparatus included in a wireless communication system having a mobile communication device configured to communicate with first and second base stations configured to calculate a received signal strength and an angle of arrival of a wireless signal from the mobile communication device comprises a position estimation unit configured to determine a calibrated position of the mobile communication device by using the received signal strength and the angle of arrival at each of the first and second base stations.
(FR) L’invention concerne un appareil d’estimation de position appartenant à un système de communication sans fil possédant un dispositif de communication mobile configuré pour communiquer avec des première et deuxième stations de base configurées pour calculer une intensité de signal reçu et un angle d’arrivée d’un signal sans fil provenant du dispositif de communication mobile, l’appareil comprenant une unité d’estimation de position configurée pour déterminer une position étalonnée du dispositif de communication mobile à l’aide de l’intensité du signal reçu et de l’angle d’arrivée au niveau de chacune des première et deuxième stations de base.
