DOI: 10.1109/tcomm.2019.2928537

Abstract: Large-scale non-geostationary orbit (NGSO) satellite communication systems (SCSs) are gaining interest from industries because of their ubiquitous wireless access and backhaul capabilities. However, the NGSO SCSs’ global downlink transmission can cause radio frequency interference (RFI)… read more here.

DOI: 10.1109/tcomm.2024.3472528

Abstract: Satellite communication systems (SCSs) have recently evolved into mega-constellations with thousands of non-geostationary orbit (NGSO) satellites. They offer an advantage of global coverage with low latency for communication and information access but impose an increased… read more here.
