Abstract[English]
A team polar decoder, TPD, (340) includes polar decoders, PPDs, (410), connected to a channel (330), and a team decision maker, TDM, (420) connected to the PPDs and a destination (350) Component polar decoders, CPDs, (410-m) decode a polar code in accordance with a polar code. Each CPD receives a noisy code block, NCB, from the channel, and decodes the NCB in consecutive steps to obtain a decoded transform input block, DTIB. Each CPD is generates, at an end of the decoding step, a candidate decoded data block, CCDB, from the DTIB by a data-demapping operation that is an inverse of a data-mapping operation applied at a polar encoder (320), then sends the CDDB to the TDM, which receives the CDDBs from the PPDs, generates a decoded data block, DDB, and sends the DDB to the destination. Thereby, the invention provides high throughput polar decoding approaching the performance of SCL or CA-SCL decoding.[French]
La présente divulgation concerne un décodeur polaire d'équipe, TPD, (340) qui comprend des décodeurs polaires, PPD, (410), connectés à un canal (330), et un dispositif de prise de décision d'équipe, TDM, (420) connecté aux PPD et un décodeur polaire de composant de destination (350), CPD, (410-m) qui décodent un code polaire selon un code polaire. Chaque CPD reçoit un bloc de code bruité, NCB, à partir du canal, et décode le NCB en étapes consécutives pour obtenir un bloc d'entrée de transformée décodé, DTIB. Chaque CPD génère, à une extrémité de l'étape de décodage, un bloc de données décodé candidat, CCDB, à partir du DTIB par une opération de démappage de données qui est un inverse d'une opération de mappage de données appliquée au niveau d'un codeur polaire (320), puis envoie la CDDB au TDM, qui reçoit les CDDB des PPD, génère un bloc de données décodé, DDB, et envoie la DDB à la destination. Ainsi, l'invention fournit un décodage polaire à haut débit approchant les performances de décodage SCL ou CA-SCL.
