Optimal bit and power loading for amplify-and-forward cooperative OFDM systems
(IEEE, 2011-03)
In this paper, we investigate bit and power allocation strategies for an orthogonal frequency division multiplexing (OFDM) cooperative network over frequency-selective fading channels. We assume amplify-and-forward relaying ...
Sensing-throughput tradeoff in cooperative spectrum sensing
(IEEE, 2012)
In the current literature on cognitive radio, it is commonly assumed that fixed time durations are assigned for spectrum sensing and data transmission. It is however possible to improve the performance by finding the best ...
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 ...
Single color networks: OFDM-based visible light broadcasting
(IEEE, 2015)
In this study, we investigate the performance of optical orthogonal frequency division multiplexing (O-OFDM) based visible light broadcasting. Although indoor spaces usually have more than one light source, most of the ...
IEEE 802.15.13-compliant visible light communications in vehicular networks
(Taylor & Francis, 2018-01)
Current research activities and standardization efforts in intelligent transportation systems (ITS) have mainly focused around the deployment of radio frequency (RF)-based communication techniques for vehicular networking. ...
Performance of OFDM-based adaptive visible light communications
(IEEE, 2017)
In this paper, we investigate the performance of a direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based adaptive transmission in the context of visible light communication (VLC). We ...
Single photon avalanche diode (SPAD) VLC system and application to downhole monitoring
(IEEE, 2014)
In this paper, it is demonstrated for the first time that the problem of continuous downhole monitoring in the oil and gas industry is effectively addressed by the use of visible light communication (VLC). As a reliable, ...
The impact of location errors on achievable rates in OFDM-based multi-user visible light communication systems
(IEEE, 2014)
Visible light communication (VLC) is a communication technology in which data is transferred by modulating the visible light intensity. VLC signals degrade significantly due to the absence of the line of sight (LOS) between ...
Kuvvetlendir-ve-aktar tipi işbirlikli haberleşme sistemlerinde zaman senkronizasyonu
(IEEE, 2010)
The synchronization problem in wireless communication systems becomes more important especially in cooperative communication systems than it is for other diversity systems because all terminals in the cooperation use their ...
End-to-end performance of mixed RF/FSO transmission systems
(IEEE, 2013-11)
In this paper, we consider a heterogenous scenario where free-space optical (FSO) and radio-frequency (RF) technologies are deployed together as a dual-hop communication system, and we investigate the end-to-end outage ...
