<p>The invention concerns a decoding method with flexible input and flexible output of a linear block code word (s) of dimension k and length n, received from a transmission channel, comprising steps which consists in: generating a list of firm words (ub) of the code close to the received code word (s), by coding a list of k-uplets obtained by firm approximation of the received word components and by changing the less reliable components; computing the jth output flexible word component by difference between the generated closest word metrics, and the generated closest word having an opposite jth component, or in default the generated least close code word. The invention also concerns an iterative method for decoding a product code word received on a transmission channel, using such decoding method with flexible input and flexible output. It enables quick and efficient decoding of a code product words, even if there is no algebraic decoder.</p> |
