Abstract[English]
Various aspects of the present disclosure relate to receiving (1502) a polar codeword comprising a set of bits and generating (1504) a permuted vector based at least in part on the polar codeword and a permutation matrix. Aspects of the disclosure may relate to determining (1506) a plurality of polar subcodes based on the permuted vector, and identifying (1508), for each polar subcode of the plurality of polar subcodes, a set of kernels, where each kernel of the set of kernels is associated with a bit pattern of a set of one or more bit patterns. Aspects of the disclosure may relate to decoding (1510) the plurality of polar subcodes using a plurality of parallel polar code component decoders, where each parallel polar code component decoder includes one or more fast decode modules to decode a corresponding kernel of the set of kernels.[French]
Divers aspects de la présente divulgation concernent la réception (1502) d'un mot de code polaire comprenant un ensemble de bits et la génération (1504) d'un vecteur permuté sur la base, au moins en partie, du mot de code polaire et d'une matrice de permutation. Des aspects de la divulgation peuvent concerner la détermination (1506) d'une pluralité de sous-codes polaires sur la base du vecteur permuté, et l'identification (1508), pour chaque sous-code polaire de la pluralité de sous-codes polaires, d'un ensemble de noyaux, chaque noyau de l'ensemble de noyaux étant associé à un motif de bits d'un ensemble d'un ou de plusieurs motifs de bits. Des aspects de la divulgation peuvent concerner le décodage (1510) de la pluralité de sous-codes polaires à l'aide d'une pluralité de décodeurs de composants de code polaire parallèles, chaque décodeur de composant de code polaire parallèle comprenant un ou plusieurs modules de décodage rapide pour décoder un noyau correspondant de l'ensemble de noyaux.
