Abstract
Visible light communication (VLC) system provides an opportunity for data transmission and its traditional use as source of illumination. Besides, dimming control is also required to achieve variable levels in some specific circumstances. Among the various modulation schemes to achieve dimming control, multiple pulse-position-modulation (MPPM) is regarded as a more spectral-efficient and energy-saving method. In this paper, we proposed the Fast Detection Algorithm for MPPM based on maximum likelihood (ML) principle, which is suitable for fast dimmable indoor VLC system. Thus, the information about transmitted data and dimming factor can be acquired instantly. Finally, error performances are provided with difference dimming levels via MATLAB simulation.
