<p>An automatic retransmit request (ARQ) telecommunications system reconstructs a first data block from one or more encoded first blocks received and stored by the system. Each encoded first block being encoded from the first data block using a forward error correction (FEC) scheme prior to reception by the system. The system includes a channel decoder configured to attempt to reconstruct the first data block from one or more of the received encoded first block and a packet controller, configured to request retransmission of the first data block as one or more subsequent encoded first blocks, when said one or more received encoded first blocks are determined to be corrupted such that the first data block cannot be reconstructed therefrom. The channel decoder further includes means for storing a flag indicative that the said first data block has been reconstructed, and means for discarding upon receipt any further encoded first blocks encoding the said first data block when the flag inidcates that the said first data block has been reconstructed.</p> |
