Visible light communication (VLC) is considered as a promising
technique for the wireless technology of the 21st century. Utilizing
Light Emitting Diode (LED) technology adds a wide area of
applications for VLC. Most important one is that VLC can provide
illumination/communication jointly. To achieve efficient
commercial VLC communication/illumination system one needs
to profit from dimming schemes/flicker. Availability of suitable
system designs and enhancing system's power requirements are
key advantages for using dimming schemes. Effective dimming
schemes/flicker are mainly achieved through several VLC based
on modulation techniques. In last few years many kinds of
literature discussed independently wide range of modulation
schemes to address the effectively previous issue. However, few
surveys for these works are presented in the field. This paper
provides an in-depth survey of VLC based dimming scheme.
Therefore, the kinds of modulation and coding techniques are
collected and categorized of more than 60 papers extending from
pioneering papers to the state of the art in the field. In addition,
research and current issues are discussed especially in which
trends in VLC based dimming/flicker.
