An apparatus and method for coding a block Low Density Parity Check (LDPC) code having a variable coding rate. The apparatus receives an information word and encodes 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 coding rate to be applied when generating the information word into the block LDPC code.

L'invention concerne un appareil et un procédé de codage d'un code de contrôle de parité de basse densité (LDPC) de blocs ayant un débit de codage variable. L'appareil reçoit un mot d'information et il code le mot d'information en un code LDPC de blocs basé sur une des première matrice de contrôle de parité et seconde matrice de contrôle de parité, en fonction du débit de codage à appliquer lors de la génération du mot d'information dans le code LDPC de blocs.
