Mitigation of adjacent channel interference in communication satellites

Abstract:

A method for carrier frequency assignment to users includes receiving, by a service provider scheduler, a service request from a user. The method further includes receiving, by the service provider scheduler, satellite beams information of a satellite. A user location corresponding to the user is determined. A service beam to service the user and a distance from a center of the service beam to the user location are determined based on the satellite beams information. The service beam is a satellite beam of a plurality of satellite beams provided by the satellite, and the satellite is in communication with the user via the service beam. Carrier frequency assignment to users is made to mitigate adjacent channel interference.
