| 摘要 |
The invention relates to methods and devices for coding and decoding coded data comprising source data (S) and redundancy data (R), said redundancy data (R) being obtained by applying, upon coding, an error corrector code to said source data, implementing a generating matrix comprising, in its systematic form, an identity matrix and an invertible matrix for switching from the source data to the redundancy data (P), the coding or decoding (12) being based on a Tanner graph which combines the graph of said error corrector code and the graph of the dual code of said error corrector code by superimposing these graphs. |
