Prominent Modulation Techniques Analysis to Dim LEDs Installed Indoors Under Visible Light Communication

There is a dare necessitate of latest and reliable communication medium to meet out the escalating wireless data traffic and the increasing demand among users in their day to day life. The medium of communique using visible light spectrum in VLC can overcome the unease circumstances prevailing on the present RF spectrum. The LEDs utilized in VLC provides productiveness, comfortability and energy saving. The control in lighting can be accomplished through dimming in the LEDs installed; which is space and application specific, and helps to achieve energy conservation in the lighting sector. The survey is to devise efficient modulation technique to dim LEDs installed indoors and to uphold a reliable, efficient and successful VLC link even at low intensities.
