  In this paper, we investigated the capacity and bit error rate (BER)
performance of Multiple Input Multiple Output (MIMO) satellite systems with
single and multiple dual polarized satellites in geostationary orbit and a
mobile ground receiving station with multiple antennas. We evaluated the
effects of both system parameters such as number of satellites, number of
receive antennas, and SNR and environmental factors including atmospheric
signal attenuations and signal phase disturbances on the overall system
performance using both analytical and spatial models for MIMO satellite
systems.
