1. A system for error-correction coding of a source of original digital data elements, comprising:

  • (a) a first systematic convolutional encoder, coupled to the source of original digital data elements, for generating a first series of coded output elements derived from the original digital data elements;

    (b) at least one interleaver, each coupled to the source of original digital data elements, for modifying the order of the original digital data elements to generate respective sets of interleaved elements; and

    (c) at least one next systematic convolutional encoder, each coupled to respective interleaved elements, each for generating a corresponding next series of coded output elements derived from a respective set of interleaved elements, each next series of coded output elements being in parallel with the first series of coded output elements;

    wherein the system for error-correction coding outputs only the first series of coded output elements and each next series of coded output elements.
