Abstract

Le procédé consiste à insérer entre les échantillons de signal fourni par un modulateur (COFDM) des échantillons dont l'amplitude est interpolée (11) entre les valeurs des échantillons voisins du train numérique fourni et à transposer (11) numériquement les échantillons de signal obtenus sur une fréquence intermédiaire sous multiple de la fréquence des échantillons interpolés avant de procéder à leur conversion sous une forme analogique (12). Application: Emetteur de radiodiffusion numérique.
