(FR) PROCÉDÉ D'AMÉLIORATION DU TEMPS DE BALAYAGE DE SIGNAUX DE SOUS-BRUIT DE FOND À FAIBLE ÉNERGIE PAR ENTRELACEMENT DE BALAYAGES À TRAVERS DE MULTIPLES CANAUX
Abstract:
(EN) A receiving device for detecting a transmitted signal from a communications entity on at least one of a predetermined set of channels, the transmitted signal having a repeating feature, the receiving device being configured to: repeatedly perform the following step (i): receive signals on a first one of the channels for a first period; correlate the signals received in each iteration of step (i) to form a correlated signal; and based on the correlated signal, estimate whether the repeating feature of the transmitted signal is present on the first channel.
(FR) L'invention concerne un dispositif de réception permettant de détecter un signal émis à partir d'une entité de communication sur au moins un canal parmi un ensemble prédéterminé de canaux, le signal émis ayant une caractéristique de répétition, le dispositif de réception étant configuré pour : effectuer de façon répétée l'étape (i) consistant à recevoir des signaux sur un premier canal parmi les canaux pendant une première période ; corréler les signaux reçus à chaque itération de l'étape (i) pour former un signal corrélé ; et sur la base du signal corrélé, estimer si la caractéristique de répétition du signal émis est présente sur le premier canal.
