Claim 10:
11. A system to receive Multi-Input Multi-Output (MIMO) feeder downlinks from a satellite, the system comprising:
Y ground antennae disposed in a manner that a MIMO reception of Y antennae downlink signals is spatially orthogonal when received by the Y ground antennae; and
a post-interference processor, based on the disposing of the Y ground antennae, the Y antennae downlink signals to generate Y gateway downlink signals that minimize channel interference for the MIMO reception at the Y ground antennae,
wherein the Y ground antennae are dominant line-of-sight (LOS) of X satellite antennae, X is greater than 1, Y is greater than 1, the X satellite antennae comprise reflector antennae disposed on one satellite, the X satellite antennae are disposed on a Geostationary Earth Orbit (GEO) satellite, and a channel capacity of the MIMO reception is greater than a channel capacity of X Single-Input Single-Output (SISO) receptions, and
wherein, to receive the Y antennae downlink signals as spatially orthogonal, the disposing spaces the Y ground antennae from one another based on Y.
