Multi-Carrier Modulation Techniques for Light Fidelity Technology

The Light-Fidelity(Li-Fi) is very new technology It is a new solution for multiple users. and the modulation techniques for this technology are reviewed in this paper. Li-Fi uses light as a carrier it is a type of wireless communication systems. Li-Fi can be used in sensitive areas without causing interference. Single carrier modulation (SCM) techniques are used in Li-Fi. Multicarrier modulation (MCM) techniques offer power, spectral and efficiency for Li-Fi. Li-Fi solves insufficiency of radio frequency bandwidth, provides security, low implementation, and cannot penetrate human body. Modulation techniques for Li-Fi technology are reviewed in this paper.
