Abstract

La présente invention concerne un procédé et un appareil de transmission/réception d'un signal. Selon cette invention, un mappeur de symbole permet de 'démapper' un premier intervalle de données de symbole parmi les données de sortie suivant un procédé de démappage de symbole correspondant à un premier procédé de mappage de symbole, à mettre à l'échelle le symbole démappé suivant la dimension de constellation du premier procédé de mappage de symbole et à produire le symbole mis à l'échelle, à démapper un second intervalle des données de symbole parmi les données de sortie suivant un procédé de démappage de symbole correspondant à un second procédé de mappage de symbole, à mettre à l'échelle le symbole démappé suivant une dimension de constellation du second procédé de mappage de symbole, à produire le symbole mis à l'échelle, et à générer les premiers et les seconds trains de bits dans un train de bits.
