1. A method of decoding a stream of data elements comprising:

  • receiving a first signal;

    performing constellation de-mapping for a first subset of the first signal;

    decoding the first subset of the first signal to produce a decoded first subset of the first signal;

    determining a set of points for constellation de-mapping for a second subset of the first signal based on the decoded first subset of the first signal;

    performing constellation de-mapping for the second subset of the first signal using the set of points;

    recovering a bit stream from the first signal based on said performing constellation de-mapping for the first subset of the first signal and based on said performing constellation de-mapping for the second subset of the first signal.
