Abstract
(EN)
A method for detecting a DRM signal using a sliding scan technique according to an embodiment of the present invention may comprise: a sliding sampling step for collecting sampling data from a plurality of DRM signals, received for each frequency band, while sliding and moving along a time axis and a frequency axis; a data storage step for temporarily storing, for each frequency band, the sampling data collected in the sliding sampling step; and a signal detection step for determining whether to detect a signal for each frequency band on the basis of the sampling data temporarily stored for each frequency band in the data storage step.
(FR)
La présente invention concerne un procédé de détection d'un signal DRM à l'aide d'une technique de balayage coulissant qui selon un mode de réalisation peut comprendre : une étape d'échantillonnage coulissant pour collecter des données d'échantillonnage à partir d'une pluralité de signaux DRM, reçus pour chaque bande de fréquence, tout en coulissant et se déplaçant le long d'un axe temporel et d'un axe de fréquence ; une étape de stockage de données pour stocker temporairement, pour chaque bande de fréquence, les données d'échantillonnage collectées dans l'étape d'échantillonnage coulissant ; et une étape de détection de signal pour déterminer s'il faut détecter un signal pour chaque bande de fréquence sur la base des données d'échantillonnage stockées temporairement pour chaque bande de fréquence dans l'étape de stockage de données.
