Method and apparatus for high symbol rate communication system with reduced overhead bandwidth

摘要

A method of providing a high symbol rate communication system with reduced overhead bandwidth includes calculating a minimum feasible aperture length at a network operations center, setting a hub demodulator subsystem to use an aperture length calculated from the minimum feasible aperture length, broadcasting the aperture length to a VSAT, and receiving an inroute data stream from the VSAT utilizing the aperture length.

主权项

1. A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a processor associated with a hub demodulator subsystem, for providing a high symbol rate communication system with reduced overhead bandwidth, to:
set an aperture length to a length calculated at a network operations center based on a minimum feasible aperture length calculated at the network operations center and slot sizes used by a desired inroute symbol rate, wherein the high symbol rate communication system uses a frame format with a frame having a frame length, the frame including a plurality of slots and an aperture which occupies at least a portion of a slot, and wherein the aperture length is shorter than the frame length; and receive an inroute data stream, from at least one Very Small Aperture Terminal (VSAT) to which the aperture length was broadcast, at the desired inroute symbol rate utilizing the aperture length.
