Tuneable and portable lighting system for Visible Light Communications (TP-VLC)

2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015
This work presents a low cost prototype implementing new IEEE 802.15.7 standard for Visible Light Communications. A commercial off-the-shelf development platform is used to implement the firmware controlling the system. The system is tested with different LED luminaires and distances achieving data rates of 100 kbit/s with Bit Error Rates between (10−7

Enhancing mobile device peripheral controls using Visible Light Communication (VLC)

2015 9th International Conference on Sensing Technology (ICST), 2015
Since its emergence, Optical communication systems have always been considered as a significantly attractive alternative to wired data transfer techniques, especially in environment where high data rate is essential in a multi-component system. Unfortunately, optical communication is still not as robust as traditional mechanisms and suffers from ...

High Efficiency Modulation Technique for Visible Light Communication (VLC)

2019 36th National Radio Science Conference (NRSC), 2019
In this paper, sparse activated subcarriers OFDM index modulation (SAS-OFDM-IM) and interpolated sparse activated subcarriers OFDM index modulation (ISAS-OFDM-IM) are proposed to improve the spectrum efficiency of OFDM modulation technique in visible light communication (VLC) systems.

Dynamic Resource Allocation for Visible Light Communications (VLC)- WiFi Heterogeneous Systems

2019 29th International Telecommunication Networks and Applications Conference (ITNAC), 2019
Visible Light Communication (VLC) systems are becoming an effective means of wireless communication with the potential to provide dense and fast connectivity at low cost. In this paper, we consider a VLC-WiFi heterogeneous system and investigate dynamic resource allocation for a multi-user environment to maximize the downlink capacity.

APPLICATION OF VISIBLE LIGHT COMMUNICATION (VLC) INVARIOUS AREAS: SURVEY

Suleyman Demirel University Bulletin Natural and Technical Sciences
Optical wireless communication allows communication of ultraviolet, infrared, or visible light to carry a signal. Visible light communication (VLC) is a member of optical wireless communication that operates in visible band from 390 nm to 750 nm range. VLC uses light emitting diodes (LED) that is pulsed at very high speed.
