“…Each scenario was specially designed to represent the most pressing problems in VLC. Variable natural conditions and their compensation are a topic for multiple teams and their research [6,9,37,105]. As fog is the most concerning problem, several teams tried to compensate its impact [47,106,107].…”

In this paper, our first attempt at visible light communication system, based on software defined radio (SDR) and implemented in LabVIEW is introduced. This paper mainly focuses on two most commonly used types of LED lights, ceiling lights and LED car lamps/tail-lights. The primary focus of this study is to determine the basic parameters of real implementation of visible light communication (VLC) system, such as transmit speed, communication errors (bit-error ratio, error vector magnitude, energy per bit to noise power spectral density ratio) and highest reachable distance. This work focuses on testing various multistate quadrature amplitude modulation (M-QAM). We have used Skoda Octavia III tail-light and Phillips indoor ceiling light as transmitters and SI PIN Thorlabs photodetector as receiver. Testing method for each light was different. When testing ceiling light, we have focused on reachable distance for each M-QAM variant. On the other side, Octavia tail-light was tested in variable nature conditions (such as thermal turbulence, rain, fog) simulated in special testing box. This work will present our solution, measured parameters and possible weak spots, which will be adjusted in the future.

“…VLC seems to be capable technology for short-range or possibly in the future even long-range communications. Future appliances vary greatly, spanning from vehicle-to-vehicle [4][5][6][7][8][9] communications, infrastructure-to-vehicle communications or simply as an alternative to typical local area networks (LAN) [10,11].…”

Vehicle-to-Everything (V2X) using Visible Light Communication (VLC) channels can be seen as an economically viable option to replace the existing modes of vehicular communications in the near future. In this paper, we have analyzed the performance of VLC based V2X communication under various environmental deterrents viz. Light Fog, Dense Fog, Light Smoke and Dense Smoke using a proof-of-concept testbed. A series of experiments were conducted to investigate the effects of environmental deterrents over VLC based Lineof-Sight as well as non-Line-of Sight V2X transmission with respect to distance and angular variations. On-Off-keying (OOK) modulation has been selected as the modulation scheme, as defined in VLC standard (IEEE 802.15.7) for the transmission of information bits between a transmitter LED and a photodiode receiver. The experimental results show the feasibility of VLC-based V2X systems with reliable data transmission under different environmental deterrents with a fairly good signal-tonoise ratio (SNR), even under dense-fog and smoke conditions where the attenuation in average optical power at the receiver, is quite high.

“…We varied their densities inside the testbed in order to have a more detailed analysis. The observed typical values of attenuation of different environmental deterrent through measurement and empirical calculations based on [7], [9] can be summarized in Table II. It can be inferred from the table that dense smoke attenuates the received optical power, more severely at the receiver as compared to the other environmental deterrents due to its highest attenuation coefficient.…”

“…Further, unlike VLC based V2X, RF based DSRC link availability is severely affected due to significant attenuation caused by buildings and other obstacles, which in turn reduces the communication-distance between vehicles. Further, RF based DSRC also experiences unwanted packet collision and end-toend delay, particularly during high traffic congestion which is rarely observed case for VLC based DSRC [7].…”
