Abstract
Signals of data streams for transmission to user equipment (UE) in spoke-and-hub configurations will utilize multiple transponders of satellites. Radiation patterns from ground terminals with distributed apertures feature orthogonal beams (OB). A tracking OB beam from a moving platform dynamically shall autonomously be formed as a shaped beam by a digital-beam-forming (DBF) network with a peak to a desired satellite, and nulls to undesired satellites to minimize mutual interferences among multiple satellite spatially. Ground hubs and mobile terminals feature “coherent” bandwidth aggregating capability from multiple available but non-contiguous slices of frequency slots in many transponders by wavefront multiplexing/demultiplexing (WF muxing/demuxing) techniques. These individual frequency slots must be dynamically selected, calibrated and equalized continuously in receivers via embedded probing signals as a part of WF muxing/demuxing techniques.
