ABSTRACT:
A multicarrier satellite communications system includes one or more satellites and one or more transmitters at generally terrestrial locations that transmit a plurality of signal carriers to the satellites which contain non-linear signal repeaters that produce inter-modulation noise or signal compression in the signal carriers. The noise is minimized/cancelled by adding to the signal carriers, at the generally terrestrial locations where the transmitters are located, noise-cancelling or signal compression-correcting signals.
