1. A method for error-correction coding of source digital data elements, comprising the steps of:

  • implementing at least two independent and parallel steps of systematic convolutional coding, each of said coding steps taking account of all of said source data elements and providing parallel outputs of distinct series of coded data elements;

    and temporally interleaving said source data elements to modify the order in which said source data elements are taken into account for at least one of said coding steps.
