    Abstract: Described herein are systems, devices, and methods that improve network communication on a high-latency network by using a low-latency network to manage return-link bandwidth. Embodiments of the systems described herein include a user terminal that is communicatively coupled to a high-latency network and a low-latency network. The user terminal is configured to communicate with a gateway routing device over the low-latency network. The user terminal requests return-link bandwidth and the gateway routing device provides a transmission schedule to the user terminal over the low-latency network. The user terminal can be configured to transmit a message over the high-latency network using the scheduled return-link bandwidth.

    Abstract: A satellite communications system and method of operation provides service to pluralities of user terminals in multiple non-overlapping user coverage areas, based on performing ground-based, end-to-end beamforming simultaneously with respect to the multiple user coverage areas. A satellite communications system and method of operation provides service to pluralities of user terminals in multiple non-overlapping user coverage areas, based on performing ground-based, end-to-end beamforming simultaneously with respect to the multiple user coverage areas. The system provides a number of simultaneous beams in the forward or reverse directions and controlling the allocation of beams to respective user coverage areas determines the capacity allocations for the respective user coverage areas. A multiplicity of transmit/receive paths onboard a satellite in the system supports the end-to-end beamforming and controlling the beam allocations is based on controlling the allocation of such paths to the respective user coverage areas.

    Abstract: Systems and methods are described that enable user terminals to eliminate or reduce the number of dummy bursts (or bursts with no data) they send. The systems and methods use two burst detectors, a first burst detector that analyzes the physical structure of the signal, and a second burst detector that analyzes the informational structure of the signal. Output from the first burst detector can be used to control operation of a signal decoder that decodes received signals. The second burst detector analyzes output from the signal decoder to determine the second burst indicator. In other words, the first burst detector can be implemented prior to decoding the received signal to provide a first estimate related to the presence or absence of a burst. This can then be used to limit the amount of processing performed by the signal decoder.
