Joint Power and Tilt Control in Satellite Constellation for NGSO-GSO Interference Mitigation
IEEE Open Journal of Vehicular Technology, 2023 The number of non-geostationary orbit (NGSO) satellite constellations is growing persistently. Accordingly, co-channel interference with geostationary orbit (GSO) networks will inevitably affect the operation of NGSO and GSO satellites in the years to ...
