Title
(EN) OFFSET LIFTING METHOD
(FR) PROCÉDÉ DE LEVAGE DÉCALÉ
Abstract
(EN)
A method and system for offset lifting is provided. In an embodiment, a method for encoding data includes receiving a K-bit source word input. The method also includes encoding the K-bit source word input according to a LDPC code, a lifting function, and a circulant size offset to generate an N-bit code word output. The circulant size and lifting function are determined according to an information length, a code rate, and a decoder. The method also includes storing the N-bit code word output in input/output memory.

La présente invention concerne un système et un procédé de levage décalé. Selon un mode de réalisation, un procédé de codage de données consiste à recevoir une entrée de mot source de K-bit. Le procédé comprend également un codage de l'entrée de mot source de K bits selon un code LDPC, une fonction de levage et un décalage de taille circulante pour générer une sortie de mot de code de N bits. La taille circulante et la fonction de levage sont déterminées selon une longueur d'informations, un débit de code et un décodeur. Le procédé consiste également à stocker la sortie de mot de code de N bits dans une mémoire d'entrée/sortie.
