Abstract
VLC(Visible Light Communication) is a new and emanating technique which uses light for communication. For indoor wireless ommunications, it is considered as a promising scheme for both information bearing communication as well as illumination. It provides high data rate performance at reduced cost. The aim of this paper is the analysis of optical power distribution and signal to noise ratio in an indoor VLC system. Analysis of power distribution and SNR is done by changing the direction of LEDs. It is observed that the noise in the optical channel link between the LED and photodetector dominates the data transmitted. Finally, simulation results and various parameters affecting the performance of VLC is also studied
