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 ...
Effect of eddy diffusivity ratio on underwater optical scintillation index
(The Optical Society, 2017-10-11)
The performance of underwater optical wireless communication systems is severely affected by the turbulence that occurs due to the fluctuations in the index of refraction. Most previous studies assume a simplifying, yet ...
Resource allocation for visible light communication systems using simulated annealing based on a problem-specific neighbor function
(IEEE, 2019)
In this paper, we consider a visible light communication (VLC) system with direct current-biased orthogonal frequency division multiplexing (DC-OFDM) and investigate resource allocation for a multi-user environment. Based ...
Mixed RF and hybrid RF/FSO relaying
(IEEE, 2015)
In this paper, we consider a mixed RF and hybrid RF/FSO system where several mobile users transmit their data over an RF link to a relay node (e.g. a small cell base station) and the relay forwards the information to a ...
Poster: on-board camera video transmission over vehicular VLC
(IEEE, 2017)
Vehicular connectivity is envisaged to extend vehicle on-board camera videos to the nearby vehicles in order to increase drivers' road awareness. This paper demonstrates the possibilities of video transmission captured by ...
Finite-SNR diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2017-03)
Network-coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. The combined use of orthogonal frequency division multiplexing (OFDM) with NCC has been further ...
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 ...
Iterative near maximum-likelihood sequence detection for MIMO optical wireless systems
(IEEE, 2010-04)
A major performance-limiting factor in terrestrial optical wireless (OW) systems is turbulence-induced fading. Exploiting the additional degrees of freedom in the spatial dimension, multiple laser transmitters combined ...
Guest editorial: Optical wireless communications
(IEEE, 2015-09)
Optical wireless communication (OWC) systems provide many advantages over radio frequency (RF) wireless technologies in some scenarios, including significantly higher data rates and a large amount of available license-free ...
