A high capacity communication satellite uses a large number of parallel beams and optical processing to effect a fully interactive, high bandwidth, high channel capacity fully switched communication system. The satellite reuses its assigned bandwidth in each of the multiple beams. The beams are formed by either RF or optical means. The specific users in each beam are then separated optically using spatial light modulation (SLM) array correlation techniques. A single large SLM, or multiple smaller SLMs in combination, may be used. The individual customers are then repositioned in the array by optical SLM mixing and recorrelation. The result is then remodulated by another SLM array used as a mixer, and then recombined to reform the appropriate outgoing beams. The entire system then becomes a fully switched, high bandwidth, high channel capacity communications network on a single satellite. |
