A method for minimizing co-channel interference on-board a satellite, the method comprising: post-compensating of an up-link signal received by the satellite, the uplink signal comprising a desired signal transmitted by a first transmitter and an interfering signal transmitted by a second transmitter, the post-compensating comprising: identifying the interfering signal based on post-compensation parameters including locations of the first transmitter and the second transmitter, carrier power levels of the desired signal and the interfering signal, and satellite antenna characteristics; determining gain relations between a satellite receiver antenna gain in a direction of the first transmitter and a satellite receiver antenna gain in a direction of the second transmitter; sampling and scaling the interfering signal at the satellite based on the determined gain relations; and estimating, based on the sampled and scaled interfering signal, a co-channel up-link interference component in the up-link signal, wherein the post-compensated up-link signal is represented by Z 1 t = DeltaR / R 22. Y 1 t, where DeltaR = (R 11.R 22 -R 12.R2 1), Y 1 (t) is the desired signal transmitted by the first transmitter, R11 is the satellite receiver antenna gain in the direction of the first transmitter, R12 is the satellite receiver antenna gain in the direction of the second transmitter, R22 is an antenna gain of another satellite receiver in the direction of the second transmitter, and R21 is an antenna gain of the other satellite receiver in the direction of the first transmitter. post-compensating of an up-link signal received by the satellite, the uplink signal comprising a desired signal transmitted by a first transmitter and an interfering signal transmitted by a second transmitter, the post-compensating comprising: identifying the interfering signal based on post-compensation parameters including locations of the first transmitter and the second transmitter, carrier power levels of the desired signal and the interfering signal, and satellite antenna characteristics; determining gain relations between a satellite receiver antenna gain in a direction of the first transmitter and a satellite receiver antenna gain in a direction of the second transmitter; sampling and scaling the interfering signal at the satellite based on the determined gain relations; and estimating, based on the sampled and scaled interfering signal, a co-channel up-link interference component in the up-link signal, identifying the interfering signal based on post-compensation parameters including locations of the first transmitter and the second transmitter, carrier power levels of the desired signal and the interfering signal, and satellite antenna characteristics; determining gain relations between a satellite receiver antenna gain in a direction of the first transmitter and a satellite receiver antenna gain in a direction of the second transmitter; sampling and scaling the interfering signal at the satellite based on the determined gain relations; and estimating, based on the sampled and scaled interfering signal, a co-channel up-link interference component in the up-link signal, wherein the post-compensated up-link signal is represented by Z 1 t = DeltaR / R 22.
