Abstract
Visible light communication (VLC) is considered as a promisingtechnique for the wireless technology of the 21st century. UtilizingLight Emitting Diode (LED) technology adds a wide area ofapplications for VLC. Most important one is that VLC can provideillumination/communication jointly. To achieve efficientcommercial VLC communication/illumination system one needsto profit from dimming schemes/flicker. Availability of suitablesystem designs and enhancing system's power requirements arekey advantages for using dimming schemes. Effective dimmingschemes/flicker are mainly achieved through several VLC basedon modulation techniques. In last few years many kinds ofliterature discussed independently wide range of modulationschemes to address the effectively previous issue. However, fewsurveys for these works are presented in the field. This paperprovides an in-depth survey of VLC based dimming scheme.Therefore, the kinds of modulation and coding techniques arecollected and categorized of more than 60 papers extending frompioneering papers to the state of the art in the field. In addition,research and current issues are discussed especially in whichtrends in VLC based dimming/flicker.
