Title (EN) DATA PROCESSING DEVICE AND DATA PROCESSING METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT DE DONNÉES
(JA) データ処理装置、及びデータ処理方法
Abstract:
(EN) This technology pertains to a data processing device and a data processing method that make it possible to ensure good communication quality when using an LDPC code to transmit data. In group-wise interleaving, an LDPC code having a code length of 64,800 bits and a code rate of 6/15, 7/15, 8/15, or 9/15 is interleaved on a per-bit-group basis, each bit group being 360 bits long. In group-wise deinterleaving, the interleaved LDPC code is restored to the original ordering thereof. This technology can be applied, for example, to data transmission or the like using an LDPC code.
(FR) La présente invention concerne un dispositif et un procédé de traitement de données qui permettent d'assurer une bonne qualité de communication lors de l'utilisation d'un code à contrôle de parité et faible densité (LDPC) pour transmettre des données. Dans un entrelacement par groupe, un code LDPC possédant une longueur de code de 64 800 bits et un débit de code de 6/15, 7/15, 8/15 ou 9/15 est entrelacé sur une base par groupe de bits, chaque groupe de bits étant long de 360 bits. Dans un désentrelacement par groupe, le code LDPC entrelacé est rétabli à son ordonnancement d'origine. Cette technologie peut être appliquée, par exemple, à la transmission de données ou analogue à l'aide 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データ処理装置、及びデータ処理方法に関する。 グループワイズインターリーブでは、符号長が64800ビットであり符号化率が6/15,7/15,8/15、又は、9/15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。
