  • Patent number: 10848235
    Abstract: Techniques are described for implementing adaptive coding and modulation (ACM) in regenerative satellite systems to adapt the modulation and/or FEC coding of transmitted waveforms to the conditions of the link. In a first implementation, ACM is implemented on an uplink from a terminal to a regenerative satellite. In this implementation, an uplink modulation and coding combination (ModCod) is estimated by the transmitting terminal based on the quality of signals received from the regenerative satellite on the downlink. In a second implementation, ACM may be implemented on a downlink from a regenerative satellite to a terminal. In this implementation, a transmit terminal may insert a field in a transmitted packet header that indicates a downlink ModCod to be used by the regenerative satellite when transmitting packets to a receiving terminal. The regenerative satellite may reencode and remodulate the packet using the ModCod indicated in the field of the packet header.

  • Patent number: 10848345
    Abstract: Data communications methods and systems for data packets transmitted via tunnel sessions. Satellite data communication system providing data communication services between two or more network node devices via a satellite or other data communication system are typically associated with round trip times that can cause delay in the exchange of data. Many conventional protocols, such as TCP, are not well designed for operating across links with such long delays. To address this and provide a more acceptable end-user experience, the system can include a common acceleration and optimization processor configured to provide various network acceleration and/or optimization functions and a tunnel processor configured to provide tunnel protocol-specific processing for multi-protocol encapsulated traffic.

  • Patent number: 10826597
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for adjusting the transmission power of satellite transceivers based on estimated interference. In some implementations, a satellite transceiver receives a data structure that specifies an interference compensation value for at least one frequency channel on which the satellite transceiver can transmit. The interference compensation value for the frequency channel is based on estimated interference imposed on satellite transmissions transmitted by the transceiver on the frequency channel. The transceiver receives data specifying a second transmit frequency channel to use for a second satellite transmission. A first interference compensation value for a first frequency channel and a second interference compensation value for the second frequency channel are identified from the data structure.
