  • partitioning a predefined number of bits into a first word and a second word;

    mapping said first word into a first symbol constellation having a first number of symbols to produce a first data signal;

    mapping said second word into a second symbol constellation having a second number of symbols to produce a second data signal, said first and second number of symbols being unequal;

    adding a third signal to said first data signal to form a first combined signal;

    adding a fourth signal to said second data signal to form a second combined signal; and

    transmitting said combined signals.
