Abstract

L’invention concerne un procédé d’estimation (200) d’un rapport signal sur bruit (« Signal-to-Noise Ratio » en anglais, l'abréviation « SNR ») d’un signal radio numérique reçu. Ledit procédé d’estimation (200) comprend une étape de détection (1211) consistant à récupérer un symbole de synchronisation reçu contenu dans le signal radio numérique reçu, et une étape d’estimation (1222) configurée pour déterminer le rapport signal sur bruit du signal radio numérique reçu, en fonction de la différence entre un premier signal de synchronisation reçu (Ŝa(t)) et un deuxième signal de synchronisation reçu (Ŝb(t)). Les premier et deuxième signaux de synchronisation reçus (Ŝa(t), Ŝb(t)) sont compris dans le symbole de synchronisation reçu. Figure pour l’abrégé : Figure 1
