Abstract[English]
Various aspects of the present disclosure relate to an enhanced encoder design (and associated signaling), such as an enhanced encoder structure for a quasi-cyclic low-density parity-check (QC-LDPC) encoder. The new encoder may enable a larger girth (e.g., a length of the shortest cycle of a Tanner graph) without adding complexity to a hardware implementation of the encoder, by using permutation matrices. Thus, the enhanced encoder may facilitate the use of short or finite-length codes with wireless communications data channels, among other benefits.[French]
Divers aspects de la présente divulgation concernent une conception de codeur améliorée (et une signalisation associée), telle qu'une structure de codeur améliorée pour un codeur de contrôle de parité à faible densité quasi-cyclique (QC-LDPC). Le nouveau codeur peut permettre un périmètre plus grand (par exemple, une longueur du cycle le plus court d'un graphe de Tanner) sans ajouter de complexité à une mise en œuvre matérielle du codeur, en utilisant des matrices de permutation. Ainsi, le codeur amélioré peut faciliter l'utilisation de codes de longueur courte ou finie avec des canaux de données de communication sans fil, entre autres avantages.
