All-optical amplify-and-forward relaying system for atmospheric channels
(IEEE, 2012-10)In this letter, we investigate the performance of a dual-hop free space optical link with an all-optical amplify-and-forward relay. We employ photon counting methodology and derive closed form expressions for the end-to-end ... -
Aperture averaging in multiple-input single-output free-space optical systems
(SPIE, 2015-06)Multiple-input single-output systems are employed in free-space optical links to mitigate the degrading effects of atmospheric turbulence. We formulate the power scintillation as a function of transmitter and receiver ... -
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 ... -
Iterative near maximum-likelihood sequence detection for MIMO optical wireless systems
(IEEE, 2010-04)A major performance-limiting factor in terrestrial optical wireless (OW) systems is turbulence-induced fading. Exploiting the additional degrees of freedom in the spatial dimension, multiple laser transmitters combined ... -
Mixed RF and hybrid RF/FSO relaying
(IEEE, 2015)In this paper, we consider a mixed RF and hybrid RF/FSO system where several mobile users transmit their data over an RF link to a relay node (e.g. a small cell base station) and the relay forwards the information to a ... -
Multi-hop relaying over the atmospheric poisson channel: outage analysis and optimization
(IEEE, 2012-03)In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ... -
Outage analysis of q-duplex RF/FSO relaying
(IEEE, 2015)In this paper, we propose and analyze a novel q-duplex radio frequency/free space optical (RF/FSO) relaying protocol for a mixed RF and hybrid RF/FSO communication system. In our scheme, several mobile users transmit their ... -
Outage performance of MIMO free-space optical systems in gamma-gamma fading channels
(IEEE, 2013)In this paper, we consider a MIMO Free-Space Optical (FSO) communication system over gamma-gamma turbulence channels and derive a closed-form analytical expression for the outage probability taking into account the effects ... -
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 ... -
Performance analysis of multiple-input multiple-output free-space optical systems with partially coherent Gaussian beams and finite-sized detectors
(SPIE, 2016)Multiple-input multiple-output (MIMO) techniques are employed in free-space optical (FSO) links to mitigate the degrading effects of atmospheric turbulence. We consider a MIMO FSO system, which consists of a radial laser ... -
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 ...
