Abstract

L'invention concerne un procédé et un appareil pour émettre et recevoir un signal. L'invention concerne un procédé pour émettre un signal consistant : à coder une correction d'erreur sans voie de retour de premières et secondes données de programme; à recevoir des informations d'identification des premières et secondes données de programme; à mapper les premières et secondes données de programme sur un premier et un second symbole de données de programme au moyen de différents procédés de mappage de symbole; à former une trame de modulation comprenant le premier et le second symbole de données de programme et un symbole pilote; à moduler la trame de modulation formée au moyen d'un procédé de multiplexage par répartition orthogonale de la fréquence (OFDM); et à émettre le signal modulé.
