Abstract: The device for decoding an incident FEC encoded packet of data within an ARQ scheme, comprises processing means for performing successive decoding processes of successive intermediate FEC code encoded packets related to said incident FEC code encoded packet, said processing means including a FEC decoder. Said processing means comprises determination means (DIL2, IM, SW1, SW2) for determining initial decoding conditions from the FEC code decoding result concerning the preceding intermediate FEC code encoded packet and from said current intermediate FEC code encoded packet, and said FEC decoder (FECD1) is adapted to perform the current FEC code decoding using said initial decoding conditions.
