Disclosed is a device and procedure for coding a block low density parity check (LDPC) code having a variable length. The a device and procedure includes receiving an information word; and coding the information word into a block LDPC code based on one of a first parity check matrix and a second parity check matrix depending on a length to be applied when generating the information word into the block LDPC code.

La présente invention a trait à un dispositif et une procédure pour le codage/décodage de bloc de code de contrôle de parité à faible densité (LPDC) à longueur de code variable. Le procédé comprend la réception d'un mot d'information; et le codage du mot d'information en un bloc de code LPDC basé sur un parmi une première matrice de contrôle de parité et une deuxième matrice de contrôle de parité en fonction de la longueur à appliquer lors de la génération du mot d'information dans le code LPDC du bloc.
