Claim Text:
1. A method for iteratively decoding a code word of a correcting code by an iterative decoding algorithm, which for each bit of said code word, at least one extrinsic information item is generated at each iteration, said method including the following steps: performing, at a decoding device, an initial step of decoding based upon said iterative decoding algorithm, simultaneously with executing said iterative decoding algorithm, for each bit of said code word, producing, at the decoding device, a criterion representing a number of oscillations, during all successive iterations of said iterative decoding algorithm, of at least one extrinsic information item or of one extrinsic information item with regard to another extrinsic information item, if the iterative decoding does not converge, modifying, at the decoding device, in said code word, only a value of the bit for which said number of oscillations is highest, to produce at least one modified code word, performing, at the decoding device, an additional decoding of said at least one modified code word based upon said iterative decoding algorithm, and outputting, at the decoding device, a decoded code word.
