1. An apparatus comprising:

  • an interleaver to interleave and delay a block of input bits, the interleaver generating interleaved input bits and delayed input bits;

    a serial-to-parallel converter coupled to the interleaver to pair consecutive bits of one of the interleaved and delayed input bits;

    a first encoder coupled to the serial-to-parallel converter to generate a first, second, and third encoded bits from the paired bits;

    a second encoder coupled to the serial-to-parallel converter to generate a fourth encoded bit; and

    a symbol generator coupled to the first and second rate encoders to generate a plurality of symbols, the symbols corresponding to combinations of input bits.
