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.
(FR) 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.
(JA) 本技術は、LDPC符号を用いたデータ伝送において、良好な通信品質を確保することができるようにする送信方法、及び、受信装置に関する。 グループワイズインターリーブでは、符号長Nが69120ビットのLDPC符号が、360ビットのビットグループ単位でインターリーブされる。グループワイズデインターリーブでは、グループワイズインターリーブ後のLDPC符号の並びが元の並びに戻される。本技術は、例えば、LDPC符号を用いたデータ伝送等を行う場合に適用できる。
