Title (EN) METHOD AND APPARATUS FOR IMPLEMENTING A LOW DENSITY PARITY CHECK CODE IN A WIRELESS SYSTEM
(FR) PROCEDE ET APPAREIL D'UTILISATION D'UN CODE DE CONTROLE DE PARITE DE FAIBLE DENSITE DANS UN SYSTEME SANS FIL
Abstract: front page image
(EN)A low density parity check (LDPC) code is used within a wireless apparatus to perform forward error correction (FEC) coding. Encoding comprises the multiplication (42) with a transpose of a porti9on (44) of a parity check matrix followed by differential encoding (46). In at least embodiment of the invention, a (2000, 1600) bit-length LDPC code is used.
(FR)L'invention concerne un code de contrôle de parité de faible densité (LDPC) utilisé dans un appareil sans fil pour effectuer un codage de correction aval des erreurs (FEC). Le codage comprend la multiplication (42) avec une transposition d'une partie (44) d'une matrice de contrôle de parité suivie d'un codage différentiel (46). Dans au moins un mode de réalisation de l'invention, un code LDPC (2000, 1600) est utilisé.
