A mobile channel model for vlc and application to adaptive system design
(IEEE, 2017-05)
In this letter, we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing, we first obtain channel impulse responses for each point over the user ...
Cooperative visible light communications
(Springer Science+Business Media, 2016)
In this chapter, we explore the concept of cooperative transmissions in the context of visible light communications (VLC). An indoor office space is considered with two light sources; the one at the ceiling is connected ...
Channel modeling for visible light communications
(Springer Science+Business Media, 2016)
In this chapter, we present a novel and realistic channel modeling approach for visible light communications that overcomes to the limitations of previous works. In our work, we consider wavelength dependency, effect of ...
Performance of MIMO enhanced unipolar OFDM with realistic indoor visible light channel models
(IEEE, 2016)
Visible light communication (VLC) involves the dual use of illumination infrastructure for high speed wireless access. Designing such optical based communication systems, realistic indoor optical channel modeling becomes ...
A European view on the next generation optical wireless communication standard
(IEEE, 2015)
Optical wireless technology uses light for mobile communications. The idea is to simultaneously combine the illumination provided by modern high-power light-emitting diodes (LEDs) with high-speed wireless communications. ...
Channel modeling and characterization for visible light communications
(IEEE, 2015-12)
In this paper, we present a comprehensive channel modeling and characterization study for visible light communications. Our study is based on ray tracing, which allows for an accurate description of the interaction of rays ...
IEEE 802.15.7r1 reference channel models for visible light communications
(IEEE, 2017)
The IEEE has established the standardization group 802.15.7r1 “Short Range Optical Wireless Communications”, which is currently in the process of developing a standard for visible light communication (VLC). As with any ...
Effect of wiring and cabling topologies on the performance of distributed MIMO OFDM VLC systems
(IEEE, 2019)
Since most indoor spaces have multiple luminaires for illumination, for visible light communication (VLC) systems, multiple-input multiple-output (MIMO) communication emerges as a natural solution to improve the data rates ...
Cooperative visible light communications with full-duplex relaying
(IEEE, 2017-06)
In this paper, we investigate cooperative visible light communication (VLC) system where an intermediate light source acts as a relay terminal. We assume that relay terminal operates in full-duplex mode. In contrast to ...
Performance characterization of underwater visible light communication
(IEEE, 2019-01)
In this paper, we investigate the performance limits of underwater visible light communication (UVLC) systems. We first develop a closed-form path loss expression as a function of transceiver parameters and water type. We ...
