1. A system for the decoding of a plurality of coded copies of the same data word, the system comprising at least a first decoding stage for iterative decoding of the data word, wherein the data word includes a series of symbols, and wherein each coded copy includes redundancy code and is received from a respective plurality of network nodes of a mesh network over respective transmission channels, and wherein the first decoding stage includes: a plurality of soft decision decoders, each soft decision decoder being arranged for decoding one of the coded copies received as decoder input, and a graph-based decoder comprising a plurality of nodes, each node of the graph-based decoder being arranged to receive the soft output value from a corresponding soft decision decoder, the graph-based decoder being constructed to determine a decoding value of the data word on the basis of the soft output values.
