Abstract

A visible light communication (VLC) system can consist of an LED as a transmitter, a photodiode as a receiver, and a microcontroller to process the information. This paper study an On-Off Keying modulation technique and a Non-Return to Zero coding to encode the information by considering the Bit Error Rate (BER) parameter for the performance indicator. The use of single and dual LED is conducted to find out their performance. The environment consideration is two different amounts of LED elements to see the effect of optical power respectively to BER measurement. The results of system measurements with the use of more LEDs turned out to have a relatively better BER value performance. The measurement of the BER value in a single LED element and dual-LED elements at a transmission rate of 100 bps and distance of 10 cm, respectively are 0.3302 and 0 (perfect). However, the maximum allowed value of BER in this research is 0.5. This is because a BER value of more than 0.5 has a greater probability of receiving incorrect data compared to receiving correct data. Moreover, the system with the use of more LEDs also results in an effective information transmission distance that more than doubles when adding system LED components at 100 bps and 1 kbps data rates. This can be used as the basis for optimizing VLC system's performance in future research.
