METHOD FOR ERROR CORRECTING ENCODING TO AT LEAST TWO PARALLEL SYSTEMATIC CONVOLUTIVE CODINGS, ITERATIVE DECODING METHOD, CORRESPONDING DECODING MODULE AND DECODER.

摘要

The field of the invention is that of the coding of digital data intended to be transmitted or broadcast, in particular in the presence of high transmission noise, and the decoding of the encoded data thus transmitted. The invention relates to a source (d) digital data error correction encoding method, implementing in parallel at least two systematic convolutional coding independent steps (11, 13), each of said steps (11, 13) of encoding taking into account all of said source data (d), and comprising at least one step (12) of temporal interleaving of said source data (d), modifying the order of taking into account said source data (d). ) for each of said coding steps (11, 13). BR/ The invention also relates to an iterative decoding method, using for decoding, at each iteration, an intermediate data obtained by combining the received data with an estimated datum during the previous iteration. / P
