Diversity-multiplexing trade-off in coherent free-space optical systems with multiple receivers
(IEEE, 2010-12)
In this paper, from an information theory point of view, we investigate the performance of a coherent freespace optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our ...
A novel statistical model for turbulence-induced fading in free-space optical systems
(IEEE, 2013)
In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed Double GG distribution, is based ...
Multi-hop coherent free-space optical communications over atmospheric turbulence channels
(IEEE, 2011)
In this paper, we investigate multi-hop relaying as an efficient fading mitigation tool for coherent free-space optical (FSO) systems over atmospheric turbulence channels. We consider an FSO relaying system with ...
Generalized maximum-likelihood sequence detection for photon-counting free space optical systems
(IEEE, 2010-12)
We investigate detection methods for on-off keying (OOK) photon-counting Free Space Optical (FSO) systems in the presence of turbulence-induced fading, assuming no channel state information at the receiver. To recover the ...
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 ...
On the performance of MIMO FSO communications over double generalized gamma fading channels
(IEEE, 2015)
A major performance degrading factor in free space optical communication (FSO) systems is atmospheric turbulence. Spatial diversity techniques provide a promising approach to mitigate turbulence-induced fading. In this ...
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 ...
