Performance Enhancement of Data Communication through Visible Light Communication Using On Off Keying

Visible Light Communication (VLC) refers to short-range optical wireless communication using visible light spectrum from 380 to 780nm and it has many advantages such as it can offer speeds up to 10GB/S. The other advancement is that the bandwidth available for visible light communication is 300THz whereas it is below 6GHz on RF communication. VLC transmits data by the intensity modulating optical source, such as light emitting diodes (LEDs) because of its energy efficiency and recent advancement in LED technology with fast nanoseconds switching time. This paper applies On Off keying to achieve a minimum bit error rate during its transmission of digital data when compared to other modulation techniques. The result shows that best performance using OOK, making it an ideal modulation technique for future visible light communication. The methodologies used for stimulation purpose are MATLAB and Lab View.
