A method is provided for encoding data to be sent to at least one receiver, including at least two identical encoding steps and at least one permutation step. Each encoding step associates a block of encoded data with a block of data to be encoded, using at least two basic codes, each code processing a subset of the data block to be encoded. The permutation step is inserted between two encoding steps, i.e. a current encoding step and a previous encoding step, such that the order of the data in a data block to be encoded by the current encoding step is different from the order of the data encoded by the previous encoding step. The permutation step implements, for a data block, a rotation applied to the data of the data block and a reversal of the order of the data of the data block. The operations can be implemented by an interleaving matrix.
