A method is provided for encoding an input digital message bearing K information symbols using a turbo-encoder forming a turbocode, the turbo-encoder including an interleaver and first and second encoders for encoding according to at least one elementary code and delivering the information symbols and redundancy symbols. With a puncturing of the symbols delivered by the turbo-encoder being done according to at least one periodic puncturing pattern of a length N, defining the puncturing period N, the interleaver distributes the information symbols of the input message into Q layers of the interleaved input message in complying with an interleaving function defined from the at least one puncturing pattern, according to the relationship: &#x3c0;(i)=Pi+S(i mod Q)mod K=Pi+(T+AQ)mod K.
