Abstract
A source terminal for communications with a destination terminal, both located near or on earth surface, via satellite links to a cluster of satellites in corresponding slightly inclined Geostationary Satellite Orbits (GSOs). The source terminal comprises a transmitter which includes a preprocessor to perform a K-muxing transform on M concurrent input data streams to generate concurrently M output data streams, M>1, each of the M output data streams being a linear combination of the M concurrent input data streams, the K-muxing transform having an inverse transform; a bank of modulators to transform the M output data streams into N signal streams destined for the destination terminal, N≤M; and a multibeam antenna system to dynamically track and communicate with the cluster of satellites. The multibeam antenna system transforms the N signal streams into shaped beams and radiates the shaped beams towards the cluster of satellites.
