Abstract
(EN)
A convolutional encoding device and method in a digital system. According to an embodiment of the present invention, a convolutional encoding device has a convolutional encoder and a puncturer. The convolutional encoder generates a subgroup of a first, a second and a third encoded symbols for each input bit using generator polynomials including g0(x) = 1 + x2 + x3 + x5 + x6 + `x7 + x8, g1(x) = 1 + x + x3 + x4 + x7 + x8, and g2(x) = 1 + x + x2 + x5 + x8, for inputting input bits to generate a symbol group of three subgroups for three successive input bits, and for generating a stream of the symbol groups. A symbol puncturer punctures the first symbol of one of three subgroups in each symbol group generated from the convolutional encoder.

L'invention concerne un dispositif et un procédé de codage de convolution dans un système numérique. Conformément à une forme d'exécution de l'invention, un dispositif de codage de convolution présente un codeur de convolution et un module de poinçonnement. Le codeur de convolution génère un sous-groupe d'un premier, d'un deuxième et d'un troisième symboles codés pour chaque bit d'entrée au moyen d'une transformation polynomiale par générateur, se présentant comme suit : g0(x) = 1 + x2 + x3 + x5 + x6 + `x7+ x8, g1(x) = 1 + x + x3 + x4 + x7 + x8, et g2(x) = 1 + x + x2 + x5 + x8, pour l'introduction de bits d'entrée en vue de générer un groupe symbole de trois sous-groupes pour trois bits d'entrée successifs, et pour générer un flux de groupes symbole. Un module de poinçonnement poinçonne le premier symbole de l'un des trois sous-groupes dans chaque groupe symbole généré par le codeur de convolution.
