20140198709 | DISTRIBUTED SATCOM APERTURE ON FISHING BOAT - Embodiments of a mobile communications system to service multiple users in fishing boats over same spectrum in a communication satellite network and a method for the system are generally described herein. 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. Comparing with many current mobile VSAT schemes via spreading transmitting power to a broader bandwidth reducing mutual interference to an acceptable level, the advanced terminals are more bandwidth efficient in utilizing space assets. Furthermore, to access reasonably low priced space assets, advanced 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 available residual frequency slots are negotiable to become “low priced” in general. The aggregated assets from slots in various transponders will function as individual virtual wideband channels. 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. Among many other benefits of WF muxing, we may utilize linearly polarized (LP) space asset to service circularly polarized (CP) mobile users.
