ARRAY PROCESSING FOR SATELLITE COMMUNICATIONS

摘要

A satellite communications system includes a plurality of satellites that generate communications data over a plurality of channels. A plurality of antennas receives the communications data over the plurality of channels generated by the plurality of satellites. Each of the antennas receives a separate signal from each of the plurality of satellites over the channels. A converter digitizes each of the separate signals from each of the plurality of satellites received at the plurality of antennas. A processor forms separate digital beams from each of the separate signals digitized by the converter.

1. A satellite communications system, comprising:
a plurality of satellites that generate communications data over a plurality of channels; a plurality of antennas that receive the communications data over the plurality of channels generated by the plurality of satellites, wherein each of the antennas receives a separate signal from each of the plurality of satellites over the channels; a converter to digitize each of the separate signals from each of the plurality of satellites received at the plurality of antennas; and a processor that forms separate digital beams from each of the separate signals digitized by the converter, wherein the processor determines a collective signal for a selected satellite by summing each of the separate digital beams associated with each of the plurality of satellites, and utilizes the separate digital beams from the non-selected satellites from the plurality of satellites to filter cross-channel interference from the collective signal.
