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 ... -
Diversity gain analysis of underwater vertical MIMO VLC links in the presence of turbulence
(IEEE, 2019)To satisfy the demands of high data rate underwater applications such as image and real-time video transmission, underwater visible light communication (UVLC) has emerged as an alternative to acoustic signaling. One of the ... -
Finite-SNR diversity gain analysis of FSO systems over gamma-gamma fading channels with pointing errors
(IEEE, 2021-06)Free space optical (FSO) communication systems are subject to turbulence-induced fading as a result of fluctuations in the refractive index. Gamma-Gamma (GG) distribution is commonly used in the literature to characterize ... -
Network-coded cooperative systems in cognitive radio networks
(IEEE, 2022-12)We study the performance of a network-coded cooperative (NCC) system in an underlay cognitive radio network (CRN). The primary network (PN) consists of a single transmitter-receiver pair, and the secondary network (SN) is ... -
Optimal relay placement and diversity analysis of relay-assisted free-space optical communication systems
(IEEE, 2013-01)Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ... -
Outage performance analysis of vertical underwater VLC links
(IEEE, 2022)In this paper, we investigate the outage performance of vertical stratified underwater optical links in the presence of moderate/strong turbulence conditions. Specifically, we consider the cascaded Gamma-Gamma turbulence ... -
Outage performance and diversity gain analysis of free-space optical multi-hop parallel relaying
(IEEE, 2013-08)In this paper, we investigate the outage performance of free-space optical mesh networks, which build upon the combination of serial (multi-hop) and parallel relaying. We assume log-normal atmospheric turbulence channels ... -
Performance analysis of MIMO free-space optical communication systems with selection combining
(IEEE, 2013)In this paper, we investigate the outage performance of a multi-input multi-output (MIMO) free-space optical (FSO) communication system with selection combining (SC). Under the assumption of log-normal distributed atmospheric ... -
Transmit laser selection for underwater visible light communication systems
(IEEE, 2019)Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission. Underwater propagation medium imposes additional ... -
Vertical underwater visible light communication links: Channel modeling and performance analysis
(IEEE, 2020-10)Underwater visible light communication (UVLC) has been introduced to support emerging high data rate applications such as real-time image and video transmission. Initial works on UVLC build upon the assumption of fixed ...
