Log Message:
Initial import of ldpc-20060208 into the Packages Collection.

        This collection of programs and modules, written in C, is
        intended to support research and education concerning Low
        Density Parity Check (LDPC) codes.  (Note, however, that the
        copyright notice no longer restricts use to these purposes). 
        These codes were invented by Robert Gallager in the early
        1960's, and re-invented and shown to have very good
        performance by David MacKay and myself in the mid-1990's.  The
        decoding algorithm for LDPC codes is related to that used for
        Turbo codes, and to probabilistic inference methods used in
        other fields.  Variations on LDPC and Turbo codes are
        currently the best practical codes known, in terms of their
        ability to transmit data at rates approaching channel capacity
        with very low error probability.
