1. A communications apparatus, comprising:

  • a transmitter that is capable of transmitting a channel across a transmission line;

    a carrier wave source that provides a carrier wave having a frequency to the transmitter; and

    a circuit that changes a characteristic of the carrier wave to cause a substantial reduction in the average power at the frequency of the carrier wave;

    wherein the circuit that changes a characteristic of the carrier wave further comprises a neutralizing signal generator that injects a neutralizing signal having a characteristic into the transmission line that neutralizes one or more sidebands at one or more sideband frequencies of the carrier wave wherein the neutralizing signal destructively interferes with the one or more sidebands at one or more sideband frequencies.
