Abstract

Li-Fi or light fidelity refers to 5G visible light communication system using light emitting diodes and\nlaser light, as a medium to high-speed communication in a similar manner as Wi-Fi . Li-Fi is a better alternative to WIFI\nin wireless communication. It has more capacity in terms of bandwidth in visible region therefore it does not poke its\nnoise in other communication which uses radio frequency range.\nHere for establishing communication between two PCs Light- Fidelity communication is used. An analog signal\ngenerated in one PC is transmitted to another PC using LI-FI transmitter and receiver. Then nonlinearity introduced in\nthe received signal is studied.
