Hybrid visible light communications (VLC) and PLC system

2017 Opto-Electronics and Communications Conference (OECC) and Photonics Global Conference (PGC), 2017
VLC needs a ubiquitous network as its backbone to avoid becoming an information isolated island. In this paper we propose and experimentally demonstrate an indoor hybrid system that integrates VLC and PLC. OFDM modulation scheme is used to maximize the transmission rate. Experiments show the system works well with the goal of full link transmission.

Passive optical receiver for visible light communication (VLC)

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
We demonstrate using solar cell as optical receiver (Rx) for visible light communication (VLC). The solar cell is low cost and can convert the VLC optical signal into electrical signal without external power supply. As the response of the solar cell is very limited; we also propose and demonstrate using pre-distortion to significantly enhance the ...

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.
