Adaptive unipolar MIMO-OFDM for visible light communications
(IEEE, 2019)
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for ...
Adaptive DCO-OFDM for underwater visible light communications
(IEEE, 2019-04)
Visible light communication (VLC) has been introduced as a complementary technology to acoustic communications for underwater applications. Underwater VLC can achieve much higher data rates sufficiently high for real-time ...
UAV-based FSO communications for high speed train backhauling
(IEEE, 2019)
In line with the increasing number of high speed train (HST) commuters and their demand for mobile data, railways operators expore means of providing high speed on-board wireless access. The data from all train cars are ...
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 ...
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 ...
Ultraviolet communications for ground-to-air links
(IEEE, 2019)
Ultraviolet (UV) communication enables non-line-of-sight (NLOS) wireless connectivity through strong molecular and aerosol scattering. Due to their NLOS nature, UV links bring robustness to blockage or shadowing and relax ...
Visible light communications: from theory to industrial standardization
(IEEE, 2019)
Visible light communication (VLC) builds upon the ubiquitous presence of LEDs and exploits the existing illumination infrastructure for wireless access. VLC provides high data rate transmission in unregulated optical ...
Sparse channel estimation for OFDM-based underwater acoustic systems in rician fading with a new OMP-MAP algorithm
(IEEE, 2019-03-15)
In this paper, a new channel estimation algorithm is proposed that exploits channel sparsity in the time domain for an orthogonal frequency division multiplexing (OFDM)-based underwater acoustical (UWA) communications ...
Vehicular visible light communications with SPAD receivers
(IEEE, 2019)
Light emitting diodes (LEDs) are increasingly used in automotive exterior lighting. The expected wide availability of LED-based front and back lights makes visible light communication (VLC) a natural vehicular connectivity ...
Mixture-kernel based post-distortion in RKHS for time-varying VLC channels
(IEEE, 2019-02)
Visible light communication (VLC) based systems are a viable green supplement to existing radio frequency based communication systems. However, it has been found that the performance of VLC based systems is impaired in ...
