ABSTRACT:
A satellite communication system is provided according to one embodiment of the invention. The satellite communication system includes a gateway with first and second antennas. The first antenna receives a signal from a first satellite that includes at least a first signal from a first user. The second antenna receives a second signal from a second satellite, that includes at least a second primary signal from a second user and a version of the first signal. The gateway may include circuitry to isolate the first signal from the second signal. The gateway may also include a combiner configured to combine the first signal from the first satellite and the first signal isolated from the second signal. Various other embodiments are disclosed that isolate a secondary signal received from a satellite and combine the secondary signal with the same signal received from other antennas at the gateway.
