Improving SINR via Joint Beam and Power Management for GEO and LEO Spectrum-Sharing Satellite Communication Systems
文献摘要：
In this paper, we investigate a geosyn-chronous earth orbit (GEO) and low earth orbit (LEO) coexisting satellite communication system. To de-crease the interference imposed on the GEO user caused by LEO satellites, we propose a joint beam-management and power-allocation (JBMPA) scheme to maximize signal-to-interference plus noise ratio (SINR) at the GEO user, whilst maintaining the on-going wireless links spanning from LEO satellites to their corresponding users. Specifically, we first ana-lyze the overlapping coverage among GEO and LEO satellites, to obtain the LEO-satellite set in which their beams impose interference on the GEO user. Then, considering the traffic of LEO satellites in the ob-tained set, we design a beam-management method to turn off and switch interference beams of LEO satel-lites. Finally, we further propose a deep Q-network (DQN) aided power allocation algorithm to allocate the transmit power for the ongoing LEO satellites in the obtained set, whose beams are unable to be man-aged. Numerical results show that comparing with the traditional fixed beam with power allocation (FBPA) scheme, the proposed JBMPA can achieve a higher SINR and a lower outage probability, whilst guar-anteeing the ongoing wireless transmissions of LEO satellites.
