摘要：In the field of coding/decoding in telecommunications networks, an error correcting decoder and associated decoding method are adapted to a mesh network. In particular, the system for the decoding of a plurality of coded copies of a data word includes at least a first decoding stage with: 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 receiving the soft output value from a corresponding decoder and the graph-based decoder determining a decoding value of said data word on the basis of said soft output values.
