Considerations on interference between FSO systems
2018 10th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2018FSO systems benefit from multi-Gbps communication speed and ease of installation and exploitation. If two or more FSO transceivers operate in the immediate vicinity, then there is the possibility of optical interference between systems that result in performance lowering.

2012 IV International Congress on Ultra Modern Telecommunications and Control Systems, 2012
The paper deals with the design of a test link for the characterization of a hybrid Free Space Optical/Radio-Frequency (FSO/RF) atmospheric channel. The ever-increasing demand on broadband connectivity, specifically in the Last-Mile networks, leads to the use of Free-Space optical systems in combination with RF systems above 100 GHz, which are able to ...

Hybrid FSO/RF-FSO Systems over Generalized Málaga Distributed Channels with Pointing Errors
2019 27th European Signal Processing Conference (EUSIPCO), 2019The combined effect of Malaga distributed atmospheric turbulence and pointing errors on the performance of a hybrid free-space optical (FSO)/ radio-frequency (RF)-FSO communication system is presented and analyzed in this paper. We considered three performance metrics, namely, outage probability, average bit error rate (BER) and average capacity.

Optimization of FSO quantum backscatter communication
Applied Optics, 2019In this paper, the free-space optics (FSO) quantum backscatter communication (QBC), inspired by the quantum illumination concept, is described. In this method, the transmitter generates entangled photon pairs. The signal photon is transmitted in the direction of the modulated retro reflector (MRR) or the tag antenna, and the idler photon is moved to ...
