Abstract:
This paper presents a practical scheme for analyzing the performance of a Visible
Light Communication (VLC) system in an indoor environment. The performance of
the visible light communication system depends on several factors such as the
distance between the transmission and receiver ends, data transmission speed,
noise and, receiver and transmitter characteristics. In the research work, the
applicability of different photodetectors was tested for different Light Emitting
Diode (LED) colors. The performance of the proposed VLC system was measured in
terms of Bit Error Rate (BER) for different bit patterns, lengths and baud rates. The
effect of background lighting and the noise generated from the circuit components
is minimized in the developed system in order to improve the accuracy of the
measured results. The results are presented for different distances between the
transmitter and receiver and the performance is compared in terms of the
maximum achievable coverage distance.
