Free-Space Optical (FSO) Satellite Networks Performance Analysis: Transmission Power, Latency, and Outage Probability
For the Toronto--Sydney inter-continental connection in an FSOSN with Starlink's Phase 1 Version 3 constellation, when the LISL range is approximately 2, 900 km, the mean network latency and mean average satellite transmission power intersect are approximately 135 ms and 380 mW, respectively.
On the Performance of UAV Relaying with Reconfigurable Antenna and Media Based Modulation in the Presence of Shadowed Fading
The results have shown that RAs can make the overall system more resilient to shadowing and fading effects in terms of error performance, and they are energy efficient.
Link Budget Analysis for Free-Space Optical Satellite Networks
The satellites in these FSOSNs will have limited energy and thereby limited power, and we investigate the effect of link distance and link margin on optical inter-satellite link transmission power, and the effect of slant distance, elevation angle, and link margin on optical uplink/downlink transmission power.
Cooperation in Space: HAPS-Aided Optical Inter-Satellite Connectivity with Opportunistic Scheduling
Issues with tracking, precision pointing, and Doppler shift are the major sources of performance loss in laser inter-satellite communication that can severely decrease the coverage and overall performance of satellite constellations.
Optical Satellite Eavesdropping
In recent years, satellite communication (SatCom) systems have been widely used for navigation, broadcasting application, disaster recovery, weather sensing, and even spying on the Earth.
HAPS-assisted Hybrid RF-FSO Multicast Communications: Error and Outage Analysis
In the former model, we propose a high altitude platform station (HAPS)-aided mixed RF/FSO/RF communication scheme where a terrestrial ground station intends to communicate with a cluster of nodes through two stratospheric HAPS systems.
HAPS Selection for Hybrid RF/FSO Satellite Networks
In the first phase of transmission, the satellite selects the HAPS node that provides the highest signal-to-noise ratio (SNR).
A Weather-Dependent Hybrid RF/FSO Satellite Communication for Improved Power Efficiency
In SatCom, radio-frequency (RF) or free-space optical (FSO) communications can be used depending on the communication environment.
Physical Layer Security Framework for Optical Non-Terrestrial Networks
In this work, we propose a new physical layer security framework for optical space networks.
On the Use of HAPS to Increase Secrecy Performance in Satellite Networks
In this paper, we investigate the secrecy performance of radio frequency (RF) eavesdropping for a high altitude platform station (HAPS) aided satellite communication (SatCom) system.
Site Diversity in Downlink Optical Satellite Networks Through Ground Station Selection
Recent advances have shown that satellite communication (SatCom) will be an important enabler for next generation terrestrial networks as it can provide numerous advantages, including global coverage, high speed connectivity, reliability, and instant deployment.
