Abstract
A method of reducing signal correlation in a symmetrical adaptive canceller link comprising spectrally inverting one of a first carrier signal and a second carrier signal by causing a spectral inversion of one of the first and second carrier signals using a modulator, transmitting the first and second carrier signals within a bandwidth to a remote receiver using a transmitting device such that a composite carrier signal results, and cancelling at least one of the first carrier signal from the composite carrier signal using a cancellation technique such that the second carrier signal results on one end of the link and the second carrier signal from the composite carrier signal using a cancellation technique such that the first carrier signal results on the opposite end of the link.
