Abstract: Systems and methods for mitigating interference from a satellite gateway antenna are disclosed herein. In an embodiment, a method for mitigating interference from a satellite gateway antenna includes determining a power flux density radiation from the satellite gateway antenna in at least one direction in a horizontal plane, mounting at least one panel at an area in the at least one direction in the horizontal plane, orienting the at least one panel to have an azimuthal rotation relative to a look direction of the satellite gateway antenna in the horizontal plane, and orienting the at least one panel to have an upward tilt such that any reflection of horizontal rays of the power flux density radiation off of the at least one panel is not in the horizontal plane.

Abstract: Various arrangements for performing transmodulation of a forward feeder link are presented. A first data stream and a second data stream can be modulated into a higher-order modulation forward feeder link having a higher-order digital modulation scheme. A satellite can receive the higher-order modulation forward feeder link. The satellite can demodulate the higher-order modulator forward feeder link into a bit stream. This bit stream may then be remodulated and retransmitted as multiple forward user links.

Abstract: An apparatus and method are disclosed for mitigating pointing errors resulting from satellite antennas. Reports are received from terminals in a beam hopping satellite communication system, and a pointing error associated with a satellite antenna is determined. The best beam for communicating with each terminal is selected based on the pointing error. A beam list containing the instantaneous traffic demand of terminals for each beam in the system is generated. An active beam set is then selected from the beam list for transmitting data during the next hop in the satellite communication system.

Abstract: A method and system for delivering services to terminals and associated edge devices in a satellite communication system. A network node remotely creates at least one service appliance within a terminal of the satellite communication system and customer premise equipment (CPE) connected to the terminal. Containerized applications are then transmitted from the network node to the service appliance. The service appliance subsequently executes the containerized application using hardware resources of the terminal and CPE. Usage of the containerized application can also be monitored.

The base station includes a plurality of multiple-input multiple-output (MIMO) transceivers. The system includes a terminal that is configured to receive the modulated signal. The above arrangement is particularly applicable to providing multichannel multipoint distribution services (MMDS) over a radio communications system.
