摘要： Methods and devices are provided for coding and decoding coded data including source data and redundancy data. The redundancy data is obtained by applying, upon coding, an error correction code to the source data, implementing a generating matrix. The generating matrix includes, in its systematic form, an identity matrix and an invertible matrix for switching from the source data to the redundancy data. The coding or decoding is based on a Tanner graph, which combines the graph of the error corrector code and the graph of the dual code of the error correction code by superimposing these graphs.
