1. In a wireless transmitter, a physical layer processor comprising:

  • a source signal including data;

    an FEC (Forward Error Correction) coder to receive the source signal and produce an enhanced source signal including data coded with error correction information;

    a demultiplexer coupled to receive the enhanced source signal from the FEC coder;

    a plurality of modem processors, each of which is coupled to a unique output of the demultiplexer to process respective portions of the enhanced source signal in independent channels;

    a summer coupled to receive outputs of the modem processors to produce an aggregate signal, the aggregate signal being a summation of the enhanced signal processed in independent channels; and

    a transmitter to transmit the aggregate signal over a carrier frequency.
