Abstract
La présente invention a notamment pour objet un dispositif de réception d'un signal radio adapté pour estimer un instant d'arrivée dudit signal radio. Le dispositif de réception comporte un module de réception adapté pour recevoir le signal radio, ainsi qu'un module de détection configuré pour : • mesurer un courant fourni par une source d'alimentation électrique au module de réception, • détecter un pic de courant mesuré par le module de détection, ledit pic de courant étant provoqué par la réception du signal radio par le module de réception, • déterminer l'instant d'arrivée du signal radio en fonction de l'instant de détection du pic de courant détecté.
