Performance Evaluation of Channel Model for Visible Light Communication

Abstract

Visible light communication (VLC) is an upcoming technique which can be used for data communication which uses visible light. This thesis, begin with a review of the basic (VLC) communication system mainly focus on the indoor and outdoor channel models, we designed a realistic indoor environment with multiple transmitters and receivers to distribute the LEDs on the channel, and the influence of various factors on the channel abroad. A comprehensive mathematical model is derived and simulated to investigate the performance of the proposed system considering the effect of different parameters such as received signal strength (RSS), Signal to Noise Ratio (SNR), distance between transmitter and receiver, and propagation delay in indoor (VLC), and Signal to Noise Ratio (SNR) with Bite Error Rate (BER) under different losses for outdoor (VLC) system. We reported a simulation program for indoor and outdoor visible light communication channel model based on MATLAB. Result showed that received signal strength and delay root mean square was better at small angle, and SNR was better at large angle, while minimum (BER) result with effect of smoke/fog was better than another effect of different losses outdoor VLC system.
