Abstract

Procédé de décodage de données reçues dans des trames, * les données reçues dans les trames ayant une modulation différentielle et un codage de convolution. Le procédé applique une démodulation turbo (17) et un désentrelacement (12, 13) ainsi qu'un décodage de convolution (20). Le désentrelacement (12, 13) se fait dans le temps avant la démodulation turbo (17), la démodulation turbo (17) et le décodage de convolution (20) se faisant selon un traitement par itération. Le décodage de convolution (20) applique au moins en partie un algorithme Viterbi à sortie souple.Method for decoding data received in frames, * data received in frames having differential modulation and convolutional coding. The method applies a turbo demodulation (17) and a deinterlacing (12, 13) as well as a convolution decoding (20). The deinterlacing (12, 13) is done in time before the turbo demodulation (17), the turbo demodulation (17) and the convolution decoding (20) being done according to an iteration processing. The convolutional decoding (20) at least partly applies a Viterbi algorithm with flexible output.
