A Radio Environment Mapping Based Spectrum Awareness for Cognitive Space Information Network with GEO and LEO Coexistence

On the Security of LEO Satellite Communication Systems: Vulnerabilities, Countermeasures, and Future Trends

“…A heuristics-based Radio Resource Management (RRM) algorithm was designed for mitigating the interference between LEO and GEO satellites by Emiliano et al [49], which was tested in a software simulator. A novel spectrum usage between GEO and LEO satellites was proposed by Wang et al [50], which struck an attractive trade-off between the design complexity and the spectrum awareness accuracy. Ge et al [51] proposed a Non-orthogonal Multiple Access (NOMA)-based GEO and LEO satellite network and employed Successive Interference Cancellation (SIC) for mitigating the interference.…”
