Abstract : As the number of users of wireless communication are soaring, radio frequency spectrum will soon become very difficult to be accessible for all users. So, another means to wireless communication is necessary to adjust the highly increasing demand for wireless traffic. Visible Light Communication (VLC) systems is an ideal alternative to the current wireless transfer of information, where light from LEDs acts as the medium for communication. In VLC systems, light-emitting diodes (LEDs) blink at a fast rate such that the change in light intensity is not noticeable to a human eye, but a photodiode is sensitive enough to the change in this light intensity. So it can detect the on-off behavior of the LED and decode the information sent by it. In this paper, we deal with the implementation of Multi-User Visible Light Communication (MU-VLC) where multiple signals are transmitted simultaneously using Time Division Multiplexing (TDM).
