Precise Measuring Test Bed for Characterization of Mode Field Distribution in Different types of Multimode Fibers
(Zeithamlová Milena Ing. - Agentura Action M, 2019)
In this paper we present experimental results from
precise measurements of mode field distribution in various
commercial multimode (MM) fiber types. We characterize the
mode field distribution by the encircled flux (EF) ...
Filter-less WDM for visible light communications using colored pulse amplitude modulation
(Optical Society of America, 2019)
This paper demonstrates, for the first time, a new wavelength-division multiplexing (WDM) scheme for visible light communications using multi-level coloured pulse amplitude modulation (M-CPAM). Unlike traditional WDM, no ...
On Optically Pre-amplified FSO-MISO Non-identical Links with Correlation: Experiment and Analysis
(American Institute of Physics and Magnetic Society of the IEEE, 2019)
In this paper, various link characteristics and bit
error rate (BER) performance of a free-space optical (FSO)
multiple-input-single-output (MISO) system with repetition cod-
ing (RC) is investigated both experimentally ...
Should Analogue Pre-Equalisers be Avoided in VLC Systems?
(IEEE, 2020)
Visible light communication (VLC) systems are highly constrained by the limited 3-dB bandwidth of light-emitting diodes (LEDs). Analogue pre-equalisers have been proposed to extend the LED's bandwidth at the cost of reduced ...
Efficient Exploitation of Radio Frequency and Visible Light Communication Bands for D2D in Mobile Networks
(IEEE, 2019)
The concept of device-to-device (D2D) communication, combining common radio frequency (RF) and visible light communication (VLC), is seen as a feasible way how to cope with spectrum crunch in the RF domain and how to ...
Experimental validation of indoor relay-assisted visible light communications for a last-meter access network
(Elsevier, 2019)
This paper provides experimental results for a relay-assisted visible light communications (VLC) link usinga white light-emitting diode (LED) for a last-meter access network. We demonstrate that a relay-based VLCscheme ...
Demonstration of a Hybrid FSO/VLC Link for the Last Mile and Last Meter Networks
(IEEE, 2019)
In this paper, a hybrid free-space optical and visible light communication (FSO/VLC) system was experimentally demonstrated as a solution to overcome the last mile and last meter access networks bandwidth bottleneck. We ...
Sandstorm effect on experimental optical camera communication
(OSA, 2021)
Sandstorms can severely affect the reliability of outdoor optical wireless communications (OWC) by diminishing large regions’ visibility. In this work, the effect of a real sandstorm on optical camera communications (OCC) ...
Statistical channel modelling of dynamic vehicular visible light communication system
(Elsevier, 2021)
This paper studies a statistical channel model for dynamic vehicular visible light communication systems. The proposed model considers the effect of variation in inter-vehicular spacing and the geometrical changes on path ...
Impact of Channel Correlation on Different Performance Metrics of OSSK-Based FSO Systems
(Institute of Electrical and Electronics Engineers, 2020)
In this paper, we study the impact of correlation on the bit error rate (BER) and the channel capacity of a free-space optical (FSO) multiple-input-multiple-output (MIMO) system employing optical space shift keying (OSSK) ...
