Abstract
(EN)
The present invention pertains to a transmission method and a reception device which make it possible to ensure excellent communication quality in data transfer using LDPC codes. In group-wise interleaving, an LDPC code having a code length N of 69,120 bits is interleaved on a bit group basis of 360 bits per group. In group-wise de-interleaving, the order of the interleaved LDPC code is restored to the original order. This invention can be applied, for example, to data transfer and the like using LDPC codes.

La présente invention concerne un procédé de transmission et un dispositif de réception qui permettent d'assurer une excellente qualité de communication dans un transfert de données au moyen de codes LDPC. Dans un entrelacement par groupe, un code LDPC ayant une longueur de code N de 69 120 bits est entrelacé sur une base de groupes de bits de 360 bits par groupe. Dans un désentrelacement par groupe, l'ordre du code LDPC entrelacé est restauré à l'ordre d'origine. Cette invention peut être appliquée, par exemple, au transfert de données, ou analogues, au moyen d'un code LDPC.
