On the performance of DCO-OFDM visible light communication systems under illumination constraints
(IEEE, 2015)
In this paper, we consider a DC-biased optical-orthogonal frequency division multiplexing (DCO-OFDM) visible light communication system and investigate its error rate performance under illumination constraints. First, we ...
Pilot-aided channel estimation on SC-PAM based visible light communications
(IEEE, 2018-07-02)
Estimation of the time-varying optical wireless channel response is crucial in order to decode received signals coherently. In this work, we investigate symbol-error-rate and mean absolute error performance of different ...
Indoor channel modelling and characterization for visible light communications
(IEEE, 2014)
In this paper, we investigate channel modeling for visible light communications using ray tracing approach. The simulation environment is created in Zemax® and enables us to specify the geometry of the environment, the ...
A framework on the performance analysis of dual-hop mixed FSO-RF cooperative systems
(IEEE, 2019-07)
Free space optical (FSO) communication systems provide line-of-sight wireless connectivity in the unlicensed optical spectrum and achieve higher data rates in comparison to their radio frequency (RF) counterparts. FSO ...
Device-to-device communication in 5G cellular networks: challenges, solutions, and future directions
(IEEE, 2014-05)
In a conventional cellular system, devices are not allowed to directly communicate with each other in the licensed cellular bandwidth and all communications take place through the base stations. In this article, we envision ...
Performance analysis of parallel relaying in free-space optical systems
(IEEE, 2015-11)
In this paper, we investigate the information theoretic performance of parallel relaying in free-space optical (FSO) communications over Gamma-Gamma fading channels. We consider an intensity modulation/direct-detection ...
On the performance of MIMO cooperative transmission for broadband vehicular networks
(IEEE, 2015-06)
In this paper, we investigate the performance of a cooperative vehicular network over a doubly selective fading channel using multiple antennas at source and destination vehicles. Under the assumption of amplify-and-forward ...
Survey on free space optical communication: a communication theory perspective
(IEEE, 2014)
Optical wireless communication (OWC) refers to transmission in unguided propagation media through the use of optical carriers, i.e., visible, infrared (IR), and ultraviolet (UV) bands. In this survey, we focus on outdoor ...
Standards for indoor optical wireless communications
(IEEE, 2015-03)
The application of Optical Wireless Communications (OWC) has grown in recent years that the whole industry would benefit from common standards to which competitive products comply. Standards are essential, particularly ...
Distance and power based experimental verification of channel model in visible light communication
(IEEE, 2019)
In this work, a channel model for line-of-sight (LOS) in visible light communication is elaborated. In the proposed channel model, there is no optical component, such as filter or lens, between the transmitting LED and the ...
