WebVLC uses On-Off Keying (OOK) and Pulse Position Modulation (PPM). But recently, a noticeable increase in the use of a number of other modulation techniques such as Digital Pulse Interval Modulation (DPIM) and Dual-header Pulse Interval Modulation (DH-PIM) to improve the efficiency in terms of both the bandwidth and power has been observed. WebMost VLC systems are based on intensity modulation/direct detection scheme where the intensity of the optical carrier is modulated. In this paper, two types of modulation schemes namely On-Off Keying (OOK) and Phase Shift Keying (PSK) are investigated. First, the transmitter and receiver circuit for both types of modulation schemes are constructed.
