Abstract: Visible Light Communication (VLC) is a promptly growing area of study and applications, due to the prospective and predicted high efficiency of bandwidth by using Light Emitting Diode (LED). This paper presents VLC systems using white LEDs for indoor applications. A Non-return Zero On-Off Keying (NRZ-OOK) schemes is used to transmit data. A prototype has been developed and demonstrated experimentally which accounted for the Line of Sight (LOS) with directed link. In this paper, received power is studied by analysing some parameters such as the distance between the transmitter and receiver, different transmitter angle, photodiode surface area and ambient light and also other parameters was considered in order to achieve good performance in video transmission. A seamless video signal transmission is observed in a testing board and parameters that
influence of VLC systems performance was tested under various environmental conditions. Based on the performance analysis, the hardware for simplex mode video signal transmission has shown that the distance able to provide good image on the screen is 78 cm.
Key words: VLC, white LED, wireless communication, NRZ-OOK
