A digital transmission method of the error-correcting coding type which includes, before a step of transmitting on a channel, a coding procedure including at least one puncturing step, and, after the transmission step, a decoding procedure including at least one depuncturing step, the coding procedure, applying a given coding scheme, generating a coded information item representing, with a certain redundancy, the useful information item and the decoding procedure estimating said useful information item by correcting transmission errors. This digital transmission method also includes a step of observing the transmission conditions and a puncturing scheme selection step for selecting, according to the at least one parameter, an optimum performance puncturing scheme amongst a plurality of predetermined puncturing schemes, the overall efficiency of the coding step and the puncturing step being a constant efficiency. The method also includes a coding scheme adaptation step which checks whether the puncturing scheme selected by the puncturing scheme selection step leads to the fill puncturing of at least one output information item of a coding step, amongst a plurality of coding steps whose association in parallel forms the coding scheme, and which, if applicable, modifies the coding scheme so that the coding step is no longer used.
