Outage performance of mixed RF-FSO systems over DGG and nakagami-m channels
(IEEE, 2020-12)
In mixed RF (radio frequency)-FSO (free space optical) systems, the FSO link is used for backhauling while RF is used for wireless access. In many practical deployment scenarios especially in urban environments, more than ...
UAV-based FSO communications for high speed train backhauling
(IEEE, 2019)
In line with the increasing number of high speed train (HST) commuters and their demand for mobile data, railways operators expore means of providing high speed on-board wireless access. The data from all train cars are ...
Generalized performance analysis of mixed RF/FSO cooperative systems
(IEEE, 2016-01)
Free space optical (FSO) links provide an efficient point-to-point wireless transmission solution. They are particularly useful for filling the connectivity gap between the radio frequency (RF) access network and the fiber ...
On the performance of multi-hop free space optical cooperative systems
(IEEE, 2018)
In this paper, we investigate the performance analysis of multi-hop free space optical (FSO) systems over Double Generalized Gamma (DGG) turbulence fading with pointing error impairments assuming both heterodyne detection ...
Composite fading model for aerial MIMO FSO links in the presence of atmospheric turbulence and pointing errors
(IEEE, 2021-06)
In this letter, we introduce accurate approximation expressions for composite fading channel model and outage probability of multiple-input multiple-output (MIMO) free space optical (FSO) link between two unmanned aerial ...
Adaptive modulation for FSO IM/DD systems with multiple transmitters and receivers
(IEEE, 2023-02)
Atmospheric turbulence is a major impairment in free space optical (FSO) communication systems. Since turbulence induced fading exhibits quasi-static characteristics, reliable feedback of channel state information is ...
Characterization of orbital angular momentum-multiplexed FSO channel in the presence of pointing errors
(IEEE, 2023)
Free space optical communication (FSO) uses laser transmitters at near-infrared wavelengths for line-of-sight wireless communication. Through the use of advanced laser beams instead of the conventional Gaussian-shaped beam, ...
