A Weather-Dependent Hybrid RF/FSO Satellite Communication for Improved Power Efficiency [PDF]
Recent studies have shown that satellite communication (SatCom) will have a fundamental role in the next generation non-terrestrial networks (NTN). In SatCom, radio frequency (RF) or free-space optical (FSO) communications can be used depending on the ...

Architectures and Key Technical Challenges for 5G Systems Incorporating Satellites [PDF]
Satellite Communication systems are a promising solution to extend and complement terrestrial networks in unserved or under-served areas. This aspect is reflected by recent commercial and standardisation endeavours. In particular, 3GPP recently initiated

Adaptive-Combining-Based Hybrid FSO/RF Satellite Communication With and Without HAPS
In recent years, a growing interest has been witnessed in the usage of free space optics (FSO) link for satellite communication (SATCOM) scenarios, as it offers much higher data rates up to gigabits per second (Gbps) compared to existing radio frequency (

Carrier Aggregation in Multi-Beam High Throughput Satellite Systems [PDF]
Carrier Aggregation (CA) is an integral part of current terrestrial networks. Its ability to enhance the peak data rate, to efficiently utilize the limited available spectrum resources and to satisfy the demand for data-hungry applications has drawn ...

Gaussian Entanglement Distribution via Satellite [PDF]
In this work we analyse three quantum communication schemes for the generation of Gaussian entanglement between two ground stations. Communication occurs via a satellite over two independent atmospheric fading channels dominated by turbulence-induced ...
