Claim 6:
7. The apparatus of claim 1, wherein the companion signal is a first companion signal of a plurality of companion signals, the companion signal generator circuitry is first companion signal generator circuitry, and:
the apparatus further includes second companion signal generator circuitry coupled to the target signal generator circuitry, the second companion signal generator circuitry configured to generate a second companion signal of the plurality of companion signals, the second companion signal having a third center frequency that is greater than (a) the first center frequency adjusted by the first threshold and less than (b) the first center frequency adjusted by the second threshold;
the adder circuitry is coupled to the second companion signal generator circuitry, the adder circuitry configured to combine the target signal, the first companion signal, the second companion signal, and other ones of the plurality of companion signals to form the composite signal; and
the transmitter circuitry is configured to transmit the composite signal to the target device.
