Abstract
A device for decoding an incident FEC encoded packet of data within an ARQ scheme. The device includes a processor or processing means for performing successive decoding processes of successive intermediate FEC code encoded packets related to the incident FEC code encoded packet. The processor or processing means includes a FEC decoder. The processor or processing means included a determination unit or determination means for determining initial decoding conditions from the FEC code decoding result concerning the preceding intermediate FEC code encoded packet and from the current intermediate FEC code encoded packet, and the FEC decoder is for performing the current FEC code decoding using the initial decoding conditions.

32. A method of decoding an incident Forward Error Correction (FEC) code encoded packet of data within an Automatic Repeat Request (ARQ) scheme, the method comprising:
-
executing successive decoding processes of successive intermediate FEC code encoded packets related to the incident FEC code encoded packet of data, each decoding process including a FEC code decoding, and where a current decoding process includes determining initial decoding conditions from a FEC code decoding result concerning a preceding intermediate FEC code encoded packet and from a current intermediate FEC code encoded packet; and
performing a current FEC code decoding using the initial decoding conditions. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
