BER performance of FSO links over strong atmospheric turbulence channels with pointing errors
(2008)In this letter, we investigate the error rate performance of free-space optical (FSO) links over strong turbulence fading channels together with misalignment (pointing error) effects. First, we present a novel closed-form ... -
An efficient power constrained transmission scheme for hybrid OW/RF systems
(2014)This paper investigates link layer transmission schemes for hybrid optical wireless (OW)/radio frequency (RF) systems with constraints on both per-link and total power consumption at the transmitter. Assuming timeslot ... -
FSO links with spatial diversity over strong atmospheric turbulence channels
(2008)Free-space optical (FSO) communication has received much attention in recent years as a cost-effective, license-free and wide-bandwidth access technique for high data rates applications. The performance of FSO communication, ... -
Inverse Gaussian Modeling of Turbulence-Induced Fading in Free-Space Optical Systems
(2011)We propose the inverse Gaussian distribution, as a less complex alternative to the classical log-normal model, to describe turbulence-induced fading in free-space optical (FSO) systems operating in weak turbulence conditions ... -
New results on turbulence modeling for free-space optical systems
(2010)In this paper, we propose a statistical channel model, named as Double-Weibull, to describe the irradiance fluctuations in moderate and strong turbulence for free-space optical (FSO) systems. The proposed stochastic model ... -
On the inverse-Gaussian shadowing
(2011)The Inverse Gaussian (IG) distribution has been recently proposed as a less complex alternative to the classical log-normal distribution to describe shadowing phenomena. This paper investigates the performance of digital ... -
Optical Wireless Communications With Heterodyne Detection Over Turbulence Channels With Pointing Errors
(2009)We study the error performance of an heterodyne differential phase-shift keying (DPSK) optical wireless (OW) communication system operating under various intensity fluctuations conditions. Specifically, it is assumed that ... -
Optical Wireless Links with Spatial Diversity over Strong Atmospheric Turbulence Channels
(2009)Optical wireless, also known as free-space optics, has received much attention in recent years as a cost-effective, license-free and wide-bandwidth access technique for high data rates applications. The performance of ... -
A simple statistical model for turbulence-induced fading in free-space optical systems
(2010)In this paper, we propose the Inverse Gaussian (IG) distribution, as a less complex alternative to Log-normal (LN), to describe turbulence-induced fading in free-space optical (FSO) systems operating in weak turbulence ... -
Throughput-Optimal Link-Layer Design in Power Constrained Hybrid OW/RF Systems
(2015)The aim of this paper is to develop link layer transmission schemes for hybrid optical wireless (OW)/radio frequency (RF) systems, with constraints on both per-link and total average power consumption at the transmitter. ...
