Abstract
In a method for cancelling interference caused by a terrestrial transmitter at a satellite receiver in a hybrid satellite-terrestrial network, a satellite receiver generates an interference cancellation signal based on a reference terrestrial signal from the terrestrial transmitter and a received over-the-air (OTA) signal. The satellite receiver then cancels the interference caused by the terrestrial transmitter by combining the interference cancellation signal with the received OTA signal. The interference cancellation signal is a modified version of the reference terrestrial signal.
