Abstract
An error-correction method for the coding of source digital data elements to be transmitted or broadcast, notably in the presence of high transmission noise, the method comprising at least two independent steps of systematic convolutional coding, each of the coding steps taking account of all of the source data elements, the method comprising at least one step for the temporal interleaving of the source data elements, modifying the order in which the source data elements are taken into account for each of the coding steps, and a corresponding iterative decoding method using, for the decoding, at each iteration, an intermediate data element obtained by the combination of the received data element with a data element estimated during the previous iteration.
