On the effects of combined atmospheric fading and misalignment on the hybrid FSO/RF transmission
(The Optical Society, 2016)
Free-space optical (FSO) communication is known for its various impairments such as atmospheric turbulence and misalignment fading. In this paper, we study the performance of an FSO link operating under combined path loss ...
Generalized performance analysis of mixed RF/FSO cooperative systems
(IEEE, 2016-01)
Free space optical (FSO) links provide an efficient point-to-point wireless transmission solution. They are particularly useful for filling the connectivity gap between the radio frequency (RF) access network and the fiber ...
Bit error rate analysis of MISO FSO systems
(Informa Group Company, 2016-05-09)
Multiple-input single-output (MISO) systems are employed in free space optical (FSO) links to mitigate the degrading effects of atmospheric turbulence. In this paper, we consider a MISO FSO system with practical transmitter ...
Information theoretical performance analysis and optimisation of cooperative underwater acoustic communication systems
(IEEE, 2016-05)
In this study, the authors investigate the information theoretical limits on the performance of single-carrier cooperative underwater acoustic communication systems in the presence of intersymbol interference. The authors ...
Performance of eU-OFDM based relay-assisted visible light communications
(IEEE, 2016)
In this paper, we consider relay-assisted visible light communication (VLC) system where intermediate light source cooperates with main light source. Following IEEE 802.15.7r VLC reference channel model, we assume presence ...
Channel modeling and characterization for visible light communications
(IEEE, 2015-12)
In this paper, we present a comprehensive channel modeling and characterization study for visible light communications. Our study is based on ray tracing, which allows for an accurate description of the interaction of rays ...
Aperture averaging in multiple-input single-output free-space optical systems using partially coherent radial array beams
(The Optical Society, 2016-06)
Multiple-input single-output (MISO) techniques are employed in free-space optical (FSO) links to mitigate the degrading effects of atmospheric turbulence. In this paper, for the MISO FSO system, a partially coherent radial ...
Effect of partial coherence on MISO FSO systems
(IEEE, 2015)
Multiple-input single-output (MISO) techniques are employed in free space optical (FSO) systems to mitigate the degrading effects of atmospheric turbulence and therefore the link reliability is improved. In this paper, we ...
Performance of MIMO enhanced unipolar OFDM with realistic indoor visible light channel models
(IEEE, 2016)
Visible light communication (VLC) involves the dual use of illumination infrastructure for high speed wireless access. Designing such optical based communication systems, realistic indoor optical channel modeling becomes ...
Performance analysis of cooperative diversity networks with imperfect channel estimation
(IEEE, 2010)
In this paper, we investigate the effect of channel estimation error on the error rate performance of a multi-relay system with amplify-and-forward relaying. We consider orthogonal relaying and study both conventional ...
