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 ...
QCD coupling constants and VDM
(AIP, 2012)
QCD sum rules for coupling constants of vector mesons with baryons are constructed.The corresponding QCD sum rules for electric charges and magnetic moments are also derived and with the use of vector-meson-dominance model ...
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 ...
Design of a quad element patch antenna at 5.8 GHz
(IEEE, 2018)
This paper presents simulation and experimental verification of a quad microstrip patch antenna that operates at 5.8 GHz. Sonnet antenna design software was used to simulate the performance of the antenna. To reduce the ...
Layered structure printed dipole antenna with integrated balun for phased array radars
(IEEE, 2018-04-24)
A Layered structure printed dipole antenna using through via-hole mechanism has been proposed for phased array radars. For the dipole a low dielectric constant Rogers 5880 substrate has been used to stabilize the structure ...
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 ...
