Satellite-enabled LTE systems in LEO constellations [PDF]
2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017 LTE-based satellite systems in LEO constellations are a promising solution for extending broadband coverage to areas not connected to a terrestrial infrastructure. However, the large delays and Doppler shifts over the satellite channel pose severe technical challenges to a traditional LTE system.

Developing and experimenting with LEO satellite constellations in OMNeT++
CoRR, 2021 In this paper, we present our work in designing and implementing a LEO satellite constellation simulation model1 within OMNeT++ and INET, which is validated by comparing the results with existing work. Our model builds upon the fundamentals of the Open Source Satellite Simulator (OS$^3$), which was ported to INET 4.3.

Physical Layer Authentication for LEO Satellite Constellations
2022 IEEE Wireless Communications and Networking Conference (WCNC), 2022 Physical layer authentication (PLA) is the process of claiming identity of a node based on its physical layer characteristics such as channel fading or hardware imperfections. In this work, we propose a novel PLA method for the inter-satellite communication links (ISLs) of the LEO satellites.
