Using LI-FI technology, bidirectional text communication is executed with visible light communication

Abstract

This paper demonstrates the installation of the visible light communication technology that uses light-emitting diodes as a transceiver module and its flourishing status at home and abroad. It also analyzes the system advantages, limitations, key technologies, characteristics, and existing gaps, looks forward to future research trends, and introduces visible light communication for laudable speed data sending, intelligent transportation for vehicle-to-vehicle communications, and however, nonorthogonal multiple access (NOMA) built on successive interference cancellation (SIC) is used to exploit multi-user interference, but this approach has an issue with its frequency spectrum, which is extremely power-attenuated and more costly. Assault is shown to significantly improve the bit error rate (BER) performance of DC optical orthogonal frequency division multiplexing (DCO-OFDM).
