1. A system for the decoding of a plurality of coded copies of a data word, comprising at least a first decoding stage, said first stage comprising: a plurality of soft decision decoders, each decoder being arranged for decoding a coded copy received as decoder input, and a graph-based decoder comprising a plurality of nodes, each node of said graph-based decoder being arranged to receive the soft output value from a corresponding decoder, the graph-based decoder being adapted to determine a decoding value of said data word on the basis of said soft output values.
