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.

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.

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.
