VLC technique uses frequencies other than radio, these are unrestricted and license free. VLC refers to short range optical wireless communication using visible light spectrum from 380-780 nm. VLC has a dual function that it is used for illumination and data communication purpose. However, many challenges like dimming, LED nonlinearity, fading, shadowing, flicker control etc. are faced by visible light communication. In this paper, the challenges are pertaining to PHY layer that includes signaling techniques illumination control, indoor channel, on user, and on LED have been discussed. The literature related to mitigation techniques to overcome these challenges has also been surveyed to provide the future direction for an energy efficient futuristic visible light communication Keywords: Visible light communication, LED, Modulation techniques, Cognitive MAC I. INTRODUCTION: Visible light communication using a light emitting diode (LED) is used for two purposes that is for wireless communications and lighting. VLC is the technology it utilizes the visible light source as transmitter, the photodiode as a signal receiving component. In VLC, Change in amplitude is so small for a naked human eye that it is un-noticeable. As LED illumination device is existed everywhere in the environment Visible light is preferred over infrared (IR) communications because it offer a compact, dual-use, energy saving solution. In section II, Various Signaling techniques are presented. In section III, various challenges are presented.
