Abstract

Il est décrit un appareil de transmission. Ledit appareil comprend : un codeur conçu pour générer un mot de code de contrôle de parité à faible densité (LDPC) à laide dun codage LDPC fondé sur une matrice de contrôle de parité; un entrelaceur conçu pour entrelacer le mot de code de LDPC; et un modulateur conçu pour cartographier le mot de code de LDPC entrelacé sur un symbole de modulation, dans lequel le modulateur est également conçu pour cartographier un bit inclus dans un groupe de bits prédéterminé à partir dune pluralité de groupes de bits qui constituent le mot de code de LDPC sur un bit prédéterminé du symbole de modulation.
