1. A method for using a phase invariant non-coherent burst coding mapping function, the method comprising:

  • selecting a weight 12 code word;

    generating a code list for all possible codes for the selected weight 12 code word;

    cycling through the codes in the code list by;

    selecting a code from the code list;

    generating codes for all possible rotational phases for the selected code;

    identifying conflicting codes that match the generated codes for the rotational phases of the selected code; and

    blacklisting one of the selected code and the identified conflicting codes;

    storing the mapping of data values for code words that are non-blacklisted; and

    using the mapping to generate code words from data.
