1. A multi-carrier modem, the modem comprising:

  • a receiver configured to de-modulate symbols from at least one of a plurality of spectrally overlapping carrier signals;

    a transmitter configured to modulate symbols onto at least one of a plurality of the spectrally overlapping carrier signals;

    a processor coupled to the transmitter, wherein the processor outputs data for transmission by the transmitter, wherein the processor applies an inverse Fourier transform to the data transmitted by the transmitter; and

    a controller programmed to multiplex both payload data and control data onto a first carrier of the spectrally overlapping carrier signals
