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.
