Title (EN) METHOD AND DEVICE FOR MULTI-SERVICE TRANSMISSION WITH FC-OFDM MODULATION AND CORRESPONDING RECEIVER
(FR) PROCÉDÉ ET DISPOSITIF DE TRANSMISSION MULTI SERVICES AVEC MODULATION FC-OFDM ET RÉCEPTEUR CORRESPONDANT
Abstract:
(EN) The present invention pertains to a method (1) implementing one and the same frequency time transform (IFFT) of size M whatever the service. The method adds (+FIXs) during a framing a cyclic extension of L = L 1 + L 2 samples to obtain a sequence ofM + L samples. The method performs a temporal filtering (WDG) according to a function f(n) of the samples n of the sequence ofM + L samples.
(FR) La présente invention se rapporte à un procédé (1) mettant en œuvre une même transformée (IFFT) fréquence temps de taille M quel que soit le service. Le procédé ajoute (+FIXs) lors d'une mise en trame une extension cyclique de L = L1 + L2 échantillons pour obtenir une séquence de M + L échantillons. Le procédé effectue un filtrage (WDG) temporel selon une fonction f(n) des échantillons n de la séquence de M + L échantillons.
