Performance test of low-complexity visible light communication system

A visible light communication (VLC) is an optical wireless communication technology that developed rapidly in recent years. The most common application of it is for indoor communication. Many researchers already conducted researches in various fields of this technology, but only a few researchers conducted the research based on the standard. Some of them conducted simulation-based but not hardware-based research. This research proposes a low-complexity system based on the IEEE 802.15.7 standard PHY I. It consists of a pair of transceivers. The transceiver consists of the LED with the lens as the transmitter and the high-speed photodiode as the receiver. This research focuses on how the PHY I-based system performs by testing the system using some parameters, which are throughput, distance, bit error rate (BER), and types of files. The expected result is that the system can send various-size data of any file with a data rate of 100 kbps, low BER, and in a far distance. This paper will explain further information in detail.
