A satellite communications system for communicating at a first frequency slot with first and second pairs of satellite transponders in linear polarization format. The system comprises a first terminal, a second terminal and a station. The first terminal receives at least one first input signal and concurrently radiates a first output signal at the first frequency slot to the first and second pairs of satellite transponders via a first beam and a second beam, respectively, in right-hand circularly polarized format. The second terminal receives at least one second input signal and concurrently radiates a second output signal at the first frequency slot to the first and second pairs of satellite transponders via a third beam and a fourth beam, respectively, in left-hand circularly polarized format. The station receives four satellite signals from the first and second pairs of transponders and recovers the at least one first input signal and the at least one second input signal using wavefront multiplexing technique.
