Abstract:
1. A method for communicating between an earth ground segment at a transmitting side and a spacecraft at a receiving side, comprising: performing a wavefront multiplexing transformation, at said transmitting side, on multiple data sub-streams and a probing signal stream into multiple wavefront multiplexed (WFM) transmission streams; amplifying, at said transmitting side, said WFM transmission streams; radiating, at said transmitting side, said amplified WFM transmission streams toward said spacecraft; orienting said spacecraft to receive said radiated WFM transmission streams at said receiving side; after said orienting said spacecraft to receive said radiated WFM transmission streams, equalizing, at said receiving side, propagation paths of said WFM transmission streams; and after said equalizing said propagation paths of said WFM transmission streams, recovering, at said receiving side, said data sub-streams and probing signal stream from said WFM transmission streams.
