<p>A satellite communications system comprising at least one satellite (4) in orbit about the Earth, and being arranged to receive a signal comprising a user uplink signal from a user terminal (2) adjacent the Earth, in the presence of co-channel interference from at least one interference source (121) adjacent the Earth, said at least one interference source having a linear polarisation orientation, the system further comprising means for interference mitigation (28, 37, 60, 80) characterised by said means being arranged to selectively exclude a component of said received signal having an orientation of polarisation related to that of said co-channel interference so as to improve the reception of the user uplink signal relative to that of said co-channel interference.</p> |
