Ergodic Capacity Analysis of Satellite Communication Systems With SAG-FSO/SH-FSO/RF Transmission
IEEE Photonics Journal, 2022 Future non-terrestrial networks aim to achieve a throughput of Terabits/s. Therefore, free-space optical (FSO) communications have been adopted as a candidate solution due to their ability to achieve an extremely high data rate.

Evaluation of FSO link throughput in Qatar
2015 4th Mediterranean Conference on Embedded Computing (MECO), 2015 Despite the vibrant advantages of Free Space Optics (FSO) technology and the variety of its applications, its widespread adoption has been hampered by rather disappointing link reliability for long-range links due to atmospheric turbulence-induced fading and sensitivity to detrimental climate conditions.

Hybrid SAG-FSO/SH-FSO/RF Transmission for Next-Generation Satellite Communication Systems
IEEE Transactions on Vehicular Technology, 2023 Recent advances demonstrate satellite communication (SatCom) as a potent enabler for future Terabit/s global connectivity. Existing SatCom systems, however, rely mostly on radio frequency (RF) transmission, whose limited available bandwidth is the main bottleneck for further data rate increases.

On robust FSO network dimensioning
2017 9th International Workshop on Resilient Networks Design and Modeling (RNDM), 2017 The presented work is motivated by Free Space Optics (FSO) communications. FSO is a well established wireless optical transmission technology considered as an alternative to radio communications for example in metropolitan wireless mesh networks. An FSO link is established by means of a laser beam between the transmitter and the receiver placed in the ...

Improved performance of hybrid optical communications system
Al-Qadisiyah Journal for Engineering Science, 2021 Frees Space Optical (FSO) system employs space to transfer information between the transmitter and receiver using light. However, the single-beam Single Input Single Output (SISO) technology is well known for being subject to air attenuation induced by ...

Shadowed FSO/mmWave Systems With Interference [PDF]
IEEE Transactions on Communications, 2019 We investigate the performance of mixed free space optical (FSO)/millimeter-wave (mmWave) relay networks with interference at the destination. The FSO/mmWave channels are assumed to follow Malaga-M/Generalized-K fading models with pointing errors in the FSO link.

WiMAX on FSO: Outage Probability Analysis [PDF]
IEEE Transactions on Communications, 2012 The transmission of multiple wireless signals over optical links has attained a great research interest nowadays. In case where optical fibers are difficult to be deployed, or installation cost is prohibited, optical wireless systems provide an efficient alternative means.
