Performance Analysis of Hybrid FSO Systems Using FSO/RF-FSO Link Adaptation [PDF]
IEEE Photonics Journal, 2018 Free-space optical (FSO) links are considered as cost-effective, noninvasive alternative to fiber optic cables for 5G cellular backhaul networking. For FSO-based backhaul networks, we propose an additional millimeter-wavelength (MMW) radio-frequency (RF)-

Wireless Energy and Information Transmission in FSO and RF-FSO Links [PDF]
IEEE Wireless Communications Letters, 2018 We propose and analyze a wireless energy and information transmission scheme in free-space optical (FSO) links. The results are presented for both quasi-static and fast-fading conditions. We derive closed-form expressions for throughput, outage probability, and optimal power allocation optimizing the system throughput/outage probability.

Quantize and Encode Relaying Through FSO and Hybrid FSO/RF Links
IEEE Transactions on Vehicular Technology, 2015 A relaying scheme that uses both radio frequency (RF) and free space optical (FSO) links is investigated. In the proposed quantize and encode relaying (QER), a mobile source broadcasts the RF signal using quadrature amplitude modulation (QAM). The relay estimates and quantizes the log-likelihood ratio (LLR) of each received bit in the symbol and ...

Cascaded FSO-VLC Communication System [PDF]
IEEE Wireless Communications Letters, 2017 The proposed cascaded free space optics (FSO)-visible light communication (VLC) system consists of multiple VLC access points which caters the end users connected via a decode and forward relay to the FSO backhaul link. The FSO link is assumed to be affected by path-loss, pointing error, and atmospheric turbulence while the end-to-end signal-to-noise ...

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.
