Multi-hop relaying over the atmospheric poisson channel
(IEEE, 2011)
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) ...
Performance analysis of free space optical links over turbulence and misalignment induced fading channels
(IEEE, 2012)
The performance of free-space optical (FSO) communication system is investigated from the information theory perspective, under the influence of atmospheric loss and channel fading due to the turbulence and pointing error. ...
Performance of cooperative amplify-and-forward protocols in vehicular ad-hoc networks
(IEEE, 2012)
Cooperative diversity is a technique where the diversity associated with spatially distributed users is exploited to overcome violent fading in wireless channels. In vehicle-to-vehicle (V2V) communication systems, where ...
Gamma-gamma türbülans kanallarında tüm-optik rölelemeli FSO sistemleri için röle seçimi
(IEEE, 2014)
Bu bildiride, tüm-optiksel çoklu-röle kablosuz optik haberleşme sistemleri için Gamma-Gamma atmosferik türbülans kanalı varsayımı altında servis dışı kalma başarımı incelenmiştir. Röleler arası katı senkronizasyon ihtiyacından ...
Outage performance and DMT analysis of DF parallel relaying in FSO IM/DD communications
(IEEE, 2012)
In this paper, we investigate the performance of cooperative diversity transmission in free-space optical (FSO) communications. We consider an FSO cooperative diversity system with a single decode-and-forward relay and a ...
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 ...
Performance analysis of MIMO FSO systems with radial array beams and finite sized detectors
(SPIE, 2014)
Multiple-input multiple-output (MIMO) systems are employed in free space optical (FSO) links to mitigate the degrading effects of atmospheric turbulence. In this paper, we consider a MIMO FSO system with practical transmitter ...
PHY layer performance evaluation of the IEEE 802.15.7 visible light communication standard
(IEEE, 2013)
The IEEE 802.15.7 standard defines a PHY layer and medium access control (MAC) layer for visible light communication and promises data rates sufficient to support audio and video multimedia services. In this paper, we first ...
Outage performance of FSO multi-hop parallel relaying
(IEEE, 2012)
In this paper, we investigate the outage performance of relay-assisted free-space optical (FSO) networks which build upon the combinations of serial and parallel relaying. We assume log-normal atmospheric turbulence channels ...
A software defined radio based data link design for VHF band wireless sensor networks
(Elsevier, 2018-10)
In this paper, we present an overall data link design for a tactical wireless sensor network operating at VHF band considering software defined radio (SDR) approach. An empirical channel modeling for the target environment ...
