Distributed MIMO for Li-Fi: Channel measurements, ray tracing and throughput analysis
(IEEE, 2021-08-15)
LiFi has been considered as a promising candidate for future wireless indoor networks. The IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models generated using the non-sequential ray tracing ...
Efficient resource allocation scheme in multi-user liFi networks based on angle oriented transceiver
(IEEE, 2021)
In this paper, an efficient resource allocation scheme in multi-user LiFi networks is proposed using the angle oriented (AO) technology at the receiver and transmitter sides. To cope with the inter-symbol and inter-user ...
Effect of sea waves on vertical underwater visible light communication links
(IEEE, 2023-04)
Underwater visible light communication (VLC) has been proposed to deal with emerging high bandwidth underwater applications. Initial research works on underwater VLC are based on the assumption that both transmitter and ...
Statistical characterization of FSO-based airborne backhaul links
(IEEE, 2023)
Backhaul solutions with large capacity and global coverage are of great importance for 6G wireless communication networks. With its ultra-large bandwidth and immunity to electromagnetic interference, free-space optical ...
Operation altitude optimization of solar-powered rotary-wing UAVs for FSO backhauling
(IEEE, 2023)
Free space optical communication (FSO) has emerged as an alternative backhauling technology. It provides a line-of-sight (LOS) link with a capacity comparable to fiber optics and much higher than those that can be supported ...
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 ...
FSO link attenuation measurement in extreme winter conditions for secure 5G applications
(SPIE, 2023)
The functionality of Free Space Optical (FSO) communication links is highly influenced by meteorological conditions such as precipitation, snowfall, and fog. In this study, we establish an FSO link and conduct experimental ...
Joint lifetime-outage optimization in relay-enabled IoT networks—A deep reinforcement learning approach
(IEEE, 2023-01)
Network lifetime maximization in Internet of things (IoT) is of paramount importance to ensure uninterrupted data transmission and reduce the frequency of battery replacement. This letter deals with the joint lifetime-outage ...
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, ...
Pilot-aided channel estimation for RIS-assisted wireless systems over time-varying fading channels
(IEEE, 2023)
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technology for improving wireless communication system performance. RISs can adjust signals' phase and amplitude, resulting in improved signal strength. ...
