Abstract[English]
Various aspects of the present disclosure relate to decoder configuration in a wireless communications system. A device using a guessing random additive noise decoding (GRAND) decoder is configured with various parameters, such as an abandonment threshold, which of multiple variants of GRAND decoders to use, whether a de-interleaving pattern is to be used by the GRAND decoder, etc. This configuration allows the same GRAND decoder to decode codewords encoded in any of a variety of different manners. Based on the configuration, the GRAND decoder receives a codeword over a communication channel and attempts to guess the noise on the communication channel. If the abandonment threshold number of guesses is made without resulting in a codeword that is included in the codebook, the decoding of the received codeword fails. An indication of the failure, and a reason for the failure, is optionally returned to the configuring device.[French]
Divers aspects de la présente divulgation concernent une configuration de décodeur dans un système de communication sans fil. Un dispositif utilisant un décodeur de décodage à bruit additif aléatoire (GRAND) d'estimation est configuré avec divers paramètres, tels qu'un seuil d'abandon, quelle variante de décodeur de GRAND parmi de multiples variantes de décodeurs de GRAND utiliser, si un motif de désentrelacement doit être utilisé par le décodeur de GRAND, etc. Cette configuration permet au même décodeur de GRAND de décoder des mots de code codés d'une manière quelconque parmi diverses manières différentes. Sur la base de la configuration, le décodeur de GRAND reçoit un mot de code sur un canal de communication et tente d'estimer le bruit sur le canal de communication. Si le nombre seuil d'abandon d'estimations est atteint sans donner un mot de code qui est inclus dans le livre de codes, le décodage du mot de code reçu échoue. Une indication de l'échec, et une raison de l'échec, sont éventuellement renvoyées au dispositif de configuration.
