Interference mitigation for a heterogeneous satellite network based on spatial angle and transmission power

摘要

Nowadays, with the explosive growth of users and devices, it is expected that new generation satellite system will support different communication demand around the world. Therefore, by increasing demand, hybrid satellite-terrestrial networks have been developed for achieving more coverage and capacity. Thus, in this paper, a LEO satellite constellation is deployed which includes LEO satellite systems and terrestrial equipment. Also, in order to manage the interference that is one of the main challenges in this network, Stackelberg game theory is used based on power control between LEO satellite systems and mobile users. To mitigate interference, two sub-games are provided based on pricing-based algorithm and convex optimization method. Finally, simulation results show that the performance of heterogeneous satellite network will be enhanced by the presented assumptions. (C) 2018 Elsevier GmbH. All rights reserved.
