Modulation techniques for light fidelity (Li⁃ Fi) are reviewed in this paper. Li⁃ Fi is the fully
networked solution for multiple users that combines communication and illumination …

The lack of wireless spectrum in the radio frequency bands has led to a rapid growth in
research in wireless networking using light, known as LiFi (light fidelity). In this paper an …

Important research efforts have been directed over the past ten years, towards exploring
alternative parts of the electromagnetic spectrum that could potentially offload a large portion …

This letter investigates the secrecy performance of a visible light communication (VLC)
system with a legitimate receiver and a group of eavesdroppers. Considering the …

Visible light communication (VLC) is a promising candidate for future indoor wireless
communication. Light emitting diodes (LEDs) are popular choices as transmitters for VLC …

Light-emitting diodes (LEDs) are changing indoor wireless communications. Visible light
communications (VLC) that use LEDs as transmitters is an emerging research area and has …

In recent times, there has been a surge in research on visible light communications (VLC). In
VLC systems, normal light emitting diode (LED) lamps are used as transmitters by …

The exceptional increase in the mobile data traffic leads to over exploitation of the radio
frequency (RF) spectrum making it to become overcrowded. This necessitates relying on …

Visible light communications is an energy efficient and cost-effective solution for indoor
wireless access. In this paper, we propose a multiple input multiple output system using …

Visible light communications (VLC), a short-range optical wireless communication scheme
using light-emitting diodes (LEDs) as transmitters, has been proposed to support multiple …
