CA 2569500

A method of encoding data using low density parity check (LDPC) code defined by a mxn parity check matrix is disclosed. More specifically, the method includes encoding input source data using the parity check matrix, wherein the parity check matrix comprises a plurality of zxz sub-matrices of which row weights and column weights are '0' or '1 '.

L'invention porte sur un procédé qui permet de coder des données à l'aide d'un code de contrôle de parité à faible densité ("low density parity check" ou LDPC) défini par une matrice de contrôle de parité mxn. En particulier, l'invention consiste à coder des données sources d'entrée en utilisant la matrice de contrôle de parité, laquelle matrice de contrôle de parité comprend une pluralité de sous-matrices zxz dont les poids des rangées et les poids des colonnes sont égaux à "0" ou "1".
