Incremental diversity order for characterization of FSO communication systems over lognormal fading channels
(IEEE, 2020-04)
Free space optical (FSO) communication systems experience atmospheric turbulence-induced fading, which is typically modelled by lognormal distribution. Since the decreasing rate of error probability over lognormal fading ...
Gamma-gamma türbülans kanallarında tüm-optik rölelemeli FSO sistemleri için röle seçimi
(IEEE, 2014)
Bu bildiride, tüm-optiksel çoklu-röle kablosuz optik haberleşme sistemleri için Gamma-Gamma atmosferik türbülans kanalı varsayımı altında servis dışı kalma başarımı incelenmiştir. Röleler arası katı senkronizasyon ihtiyacından ...
Performance analysis of MIMO FSO systems with radial array beams and finite sized detectors
(SPIE, 2014)
Multiple-input multiple-output (MIMO) systems are employed in free space optical (FSO) links to mitigate the degrading effects of atmospheric turbulence. In this paper, we consider a MIMO FSO system with practical transmitter ...
Asymptotic performance of generalized transmit laser selection over lognormal turbulence channels
(IEEE, 2020-08)
In free space optical communication systems, transmit laser selection (TLS) has been proposed as an efficient fading-mitigation technique over turbulence channels. In TLS, the transmitter is equipped with a number of laser ...
A custom-design atmospheric channel emulator for the performance evaluation of free space optical communication systems
(IEEE, 2017)
In this paper, we present our custom design atmospheric channel emulator for free space optical (FSO) system evaluations in a controlled environment. Our emulator is in the form of an atmospheric chamber with dimensions ...
Optical wireless communications – an emerging technology
(IEEE, 2014)
Optical wireless communication (OWC) enables wireless connectivity using infrared, visible or ultraviolet bands. With its powerful features such as high bandwidth, low cost and operation in an unregulated spectrum, OWC can ...
Adaptive free space optical communication system with multiple apertures
(2016)
In the current literature on free space optical (FSO) communication, typically open-loop designs are considered where the knowledge of channel state information is only available at the receiver. This is mostly favorable ...
Feedback-free adaptive modulation selection algorithm for FSO systems
(IEEE, 2021-09)
Free space optical (FSO) communication systems experience turbulence-induced fading. As a possible solution to mitigate the effects of fading, adaptive transmission that allows the adjustment of transmission parameters ...
Drizzle attenuation model for visible and infrared wavelengths
(IEEE, 2022)
In an outdoor environment, the transmitted optical signal is affected by the atmospheric particles that may scatter or absorb light such as drizzle, rain, snow, fog, and aerosols. Various earlier studies have attempted to ...
Aerosol attenuation model for high altitude UAV-based FSO links
(IEEE, 2022)
Free space optical (FSO) communication is well positioned to address connectivity needs in ground-UAV, inter-UAV and UAV-ground links. An accurate performance analysis of airborne FSO links requires the use of proper path ...
