Abstract

L'invention concerne un appareil d'émission. L'appareil d'émission comprend: un codeur configuré pour générer un mot de code avec vérification de parité à basse densité (LDPC) par codage LDPC basé sur une matrice de vérification de parité; un entrelaceur configuré pour entrelacer le mot de code LDPC; et un modulateur configuré pour faire correspondre le mot de code LDPC entrelacé à un symbole de modulation, le modulateur étant en outre configuré pour faire correspondre un bit compris dans un groupe prédéterminé bits parmi une pluralité de groupes de bits constituant le mot de code LDPC à un bit prédéterminé du symbole de modulation.
