<p>The invention relates to a method for decoding error correcting codes, wherein a decoded data block is associated with coded data according to a global code comprising at least two sub-codes (Ri). According to the invention, an irregular bipartite graph is associated with the global code, the decoding method is iterative, and a data block to be decoded is distributed between a plurality of disjointed memory banks (Mi) which can be independently addressed. The inventive method also comprises, at each iteration, a stage for feeding in parallel at least two decoders (671, 672, 67i, 67P) which respectively correspond to at least one of the sub-codes, in terms of the data to be decoded, the data to be decoded being extracted in parallel from at least two of the memory banks (Mi) in order to feed the same amount of decoders, and each decoder is sequentially fed with the data to be decoded corresponding thereto. The invention also relates to a corresponding coding method, corresponding coding/decoding devices and a corresponding signal.</p> |
