Abstract

L'invention concerne un appareil radio doté d'un nouveau procédé de modulation 'Comb Interleaved Frequency Division Multiplex' (Multiplexage par division de fréquence et entrelacement en peigne - CIFDM), qui combine les avantages de la modulation OFDM connue et les avantages des modulations classiques sur une seule porteuse. Le flux de données à envoyer est divisé en deux blocs de porteuses multiples qui sont envoyés en étant entrelacés l'un dans l'autre avec décalage de fréquence et décalage temporel. Pour chaque sous-porteuse séparée d'un bloc, on utilise ainsi une modulation classique avec un système de filtre adapté, et l'intervalle de garde disparaît. Le rendement spectral est ainsi considérablement accru par le fait que l'on insère un passage artificiel par zéro pour chaque symbole de modulation. Pendant ce passage par zéro, l'autre bloc est transmis et est séparé dans le récepteur par un inverseur synchrone.
