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 ...
Fast parallel prefix logic circuits for n2n round-robin arbitration
(Elsevier, 2012-08)
An n2n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input. It picks the first 1 and outputs its index in one-hot encoding. RRA aims to be fair to its inputs and maintains ...
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 ...
Multi-user visible light communications: State-of-the-art and future directions
(IEEE, 2018)
Visible light communications (VLC) builds upon the dual use of existing lighting infrastructure for wireless data transmission. VLC has recently gained interest as cost-effective, secure, and energy-efficient wireless ...
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 ...
Dağıtık bir openflow kontrol birimi mimarisi
(IEEE, 2012)
Considering the modern internet traffic rates, the network architecture is of particular importance as the running services itself. On the other hand, due to the increasing complexity and black-box structure of the available ...
Spectrum sensing of correlated subbands with colored noise in cognitive radios
(IEEE, 2012)
In this paper, we consider the problem of wideband spectrum sensing by using the correlation among the observation samples in different subbands. The Primary User (PU) signal samples in occupied subbands are assumed to be ...
Visible light channel modeling for gas pipelines
(IEEE, 2018-04)
In this paper, we explore the use of visible light communication as a means of wireless monitoring in gas pipelines. In an effort to shed light on the communication limits in the presence of gas, we create a three-dimensional ...
