Title (EN) CONVOLUTIONAL TURBO CODING METHOD AND DEVICE FOR IMPLEMENTING THE CODING METHOD
(FR) PROCÉDÉ DE TURBOCODAGE DE CONVOLUTION ET DISPOSITIF DE MISE EN ŒUVRE DU PROCÉDÉ DE CODAGE
Abstract:
(EN) A method and apparatus for Convolutional Turbo Coding (CTC), and an apparatus for a turbo encoder are provided. The method for CTC includes the steps of encoding information bits A and B using a constituent encoder, and outputting parity sequences Y1 and W1, interleaving the information bits A and B using a CTC interleaver to obtain information bits C and D, and encoding the interleaved information bits C and D using the constituent encoder to obtain parity sequences Y2 and W2, interleaving the information bits A and B, the parity sequences Y1 and W1 and the parity sequences Y2 and W2, respectively, wherein the bits in at least one of a bit group constituted of the information bits A and B, a bit group constituted of the sequences Y1 and W1, and a bit group constituted of the sequences Y2 and W2 are alternately mapped to bits of constellation points with high reliability and low reliability and puncturing the interleaving result to obtain the encoded bit sequences.
(FR) L'invention concerne un procédé et un appareil de turbocodage de convolution (CTC), et un appareil pour un turboencodeur. Le procédé de CTC comprend les étapes consistant à encoder des bits d'informations A et B en utilisant un encodeur constitutif, et délivrer des séquences de parité Y1 et W1, entrelacer les bits d'informations A et B en utilisant un entrelaceur CTC pour obtenir des bits d'informations C et D, et encoder les bits d'informations C et D entrelacés en utilisant l'encodeur constitutif pour obtenir des séquences de parité Y2 et W2, entrelacer les bits d'informations A et B, les séquences de parité Y1 et W1 et les séquences de parité Y2 et W2, respectivement, les bits dans un groupe de bits constitué des bits d'informations A et B et/ou un groupe de bits constitué des séquences Y1 et W1 et/ou un groupe de bits constitué des séquences Y2 et W2 étant mappés alternativement vers des bits de points de constellation avec une fiabilité élevée et une faible fiabilité, et percer le résultat d'entrelacement pour obtenir les séquences de bits encodées.
