Title (EN) TURBO PRODUCT CODE BASED ON POLAR CODES
(FR) CODEUR, DÉCODEUR ET ÉMETTEUR
Abstract:
(EN) An encoder for encoding source information into an encoded codeword used in a communication channel includes a data input to receive source data, a processor, and a memory to store an encoder program. The encoder program makes the processor to encode the source data into a turbo product coding (TPC) structure, and the TPC structure comprises a data block (90) corresponding to the source data, a first parity block (190) including a first column part (191), a first corner part (192) and a first bottom part (193), the first parity block being arranged so as to cover a right end column of the data block, a right bottom corner of the data block and a bottom row of the data block by the first column part, the first corner part and the first bottom part, and a second parity block (195) having a row parity block (196), a joint parity block (197) and a column parity block (198). The first parity block may be obtained by BCH encoding of the data block (outer encoding). This is followed by a (inner) turbo polar code generating the second parity block.
(FR) L'invention concerne un codeur permettant de coder des informations source en un mot de code codé destiné à être utilisé dans un canal de communication, ledit codeur comprenant une entrée de données pour recevoir des données source, un processeur et une mémoire pour stocker un programme de codeur. Le programme de codeur amène le processeur à coder les données source dans une structure de codage de produit turbo (TPC), ladite structure TPC comprenant un bloc de données correspondant aux données source, un premier bloc de parité comprenant une première partie de colonne, une première partie d'angle et une première partie de fond, le premier bloc de parité étant conçu de manière à recouvrir une colonne à l'extrémité droite du bloc de données, un coin inférieur droit du bloc de données et une rangée inférieure du bloc de données au moyen de la première partie de colonne, de la première partie d'angle et la première partie de fond, un second bloc de parité comprenant un bloc de parité de rangée, un bloc de parité de jonction et un bloc de parité de colonne.
