VLC system implementation with white LEDs

Visible light communication (VLC) is a burgeoning mode of wireless communication by using light-emitting diode (LED) as light source, which can realize communication and lighting simultaneously. The VLC technology has been attracting a huge amount of interest because of the huge bandwidth and widespread using LEDs for energy efficiency. In this paper, an indoor point-to-point VLC system is realized. The program bases on the CP1222 agreement of VLC. The design of system is realized by choosing 4.8 Kbit/s as the system transmission rate, using 4PPM modulation mode and Field-Programmable Gate Array (FPGA) as system microcontroller unit (MCU) and adopting intensity modulation/direct detection as a practical transmission. The system realizes the transmission of text data, and the test results show that the transmitted data is accurate and reliable at the same time.
