Title (EN) CRC AIDED DECODING OF POLAR CODES
(FR) DÉCODAGE ASSISTÉ PAR CRC DE CODES POLAIRES
Abstract:
(EN) Embodiments of the present disclosure provide methods and devices for data processing in a communication system. The method described herein comprises: dividing a plurality of information bits to be encoded into at least a first segment and a second segment (210). The method further comprises: encoding the first segment with a first check code to generate a first encoded sequence (220); and encoding the second segment with a second check code to generate a second encoded sequence (230). The method further comprises: cascading the first and second encoded sequences to form a cascaded sequence (240). The method further comprises: performing polar encoding on the cascaded sequence (250). At the receiving end, the check codes may be used to provide for early termination in list decoding of the polar code.
(FR) Des modes de réalisation de la présente invention concerne des procédés et dispositifs de traitement de données dans un système de communication. Le procédé décrit ici consiste à diviser une pluralité de bits d'informations devant être codés en au moins un premier segment et un second segment (210). Le procédé consiste en outre à coder le premier segment à l'aide d'un premier code de vérification pour générer une première séquence codée (220); et à coder le second segment à l'aide d'un second code de vérification pour générer une seconde séquence codée (230). Le procédé consiste encore à mettre en cascade les première et seconde séquences codées pour former une séquence en cascade (240). Le procédé consiste de surcroît à exécuter un codage polaire sur la séquence en cascade (250). Au niveau de l'extrémité de réception, les codes de vérification peuvent être utilisés pour permettre un achèvement précoce dans le décodage de liste du code polaire.
