1. A method for estimating an information vector containing information bits at a receiver, the method comprising the steps of:

  • receiving a signal vector corresponding to information bits and parity bits;

    separating the received signal vector into two groups, a first group comprising signals corresponding to the information bits and one or more parity bits, a second group corresponding to a remainder of the parity bits;

    passing the first group to a first decoder;

    passing the second group to a second decoder;

    iteratively decoding by passing messages between the decoders, where the decoders are separated by an interleaver and a de-interleaver; and

    producing an estimate of the information vector from the output of the first decoder.
