Relay selection in dual-hop vehicular networks
(IEEE, 2011-02)
In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks ...
Adaptive bit loading for multi-relay cooperative orthogonal frequency division multiple with imperfect channel estimation
(IEEE, 2012-08-14)
In this study, the authors introduce an adaptive bit loading scheme for an amplify-and-forward orthogonal frequency division multiple cooperative system with relay selection. The proposed bit loading scheme maximises the ...
Performance analysis of MIMO free-space optical communication systems with selection combining
(IEEE, 2013)
In this paper, we investigate the outage performance of a multi-input multi-output (MIMO) free-space optical (FSO) communication system with selection combining (SC). Under the assumption of log-normal distributed atmospheric ...
Novel channel models for visible light communications
(SPIE, 2015-02-07)
In this paper, we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ...
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 ...
