Load Balancing in Non-Terrestrial Networks Using Free Space Optical Inter-satellite Links
Abid Afridi, Alexis A. Dowhuszko, Jevgenij Krivochiza +2
Non-terrestrial networks (NTNs) increasingly rely on non-geostationary (NGSO) constellations that combine radio frequency (RF) feeder links (FLs) with free space optical (FSO) inte…
Demonstrator Testbed for Effective Precoding in MEO Multibeam Satellites
Jorge L. González-Rios, Liz Martínez Marrero, Juan Duncan +6
The use of communication satellites in medium Earth orbit (MEO) is foreseen to provide quasi-global broadband Internet connectivity in the coming networking ecosystems. Multi-user…
Optimal Linear Precoding Under Realistic Satellite Communications Scenarios
Geoffrey Eappen, Jorge Luis Gonzalez, Vibhum Singh +10
In this paper, optimal linear precoding for the multibeam geostationary earth orbit (GEO) satellite with the multi-user (MU) multiple-input-multiple-output (MIMO) downlink scenario…
ML-based PBCH symbol detection and equalization for 5G Non-Terrestrial Networks
Inés Larráyoz-Arrigote, Marcele O. K. Mendonca, Alejandro Gonzalez-Garrido +6
This paper delves into the application of Machine Learning (ML) techniques in the realm of 5G Non-Terrestrial Networks (5G-NTN), particularly focusing on symbol detection and equal…
Harnessing the Power of Swarm Satellite Networks with Wideband Distributed Beamforming
Juan Carlos Merlano Duncan, Vu Nguyen Ha, Jevgenij Krivochiza +6
The space communications industry is challenged to develop a technology that can deliver broadband services to user terminals equipped with miniature antennas, such as handheld dev…
Architectures and Synchronization Techniques for Distributed Satellite Systems: A Survey
Liz Martinez Marrero, Juan C. Merlano Duncan, Jorge Querol +6
Cohesive Distributed Satellite Systems (CDSS) is a key enabling technology for the future of remote sensing and communication missions. However, they have to meet strict synchroniz…
End-to-end Precoding Validation over a Live GEO Satellite Forward Link
Jevgenij Krivochiza, Juan Carlos Merlano Duncan, Jorge Querol +5
In this paper we demonstrate end-to-end precoded multi-user multiple-input single-output (MU-MISO) communications over a live GEO satellite link. Precoded communications enable ful…
Interference Exploitation via Symbol-Level Precoding: Overview, State-of-the-Art and Future Directions
Ang Li, Danilo Spano, Jevgenij Krivochiza +7
Interference is traditionally viewed as a performance limiting factor in wireless communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of work…
Low Complexity Symbol-Level Design for Linear Precoding Systems
Jevgenij Krivochiza, Ashkan Kalantari, Symeon Chatzinotas +1
The practical utilization of the symbol-level precoding in MIMO systems is challenging since the implementation of the sophisticated optimization algorithms must be done with reaso…
