Performance Evaluation of Visible Light Communication System based on Optical Power Distribution with Channel Delay Spread and SNR
With the advancement of the light-emitting diode (LED), the use of light as a communication medium has progressed in new directions. Visible light communication (VLC) makes use of white light emitting diodes (LED), which send data through glimmering light at speeds imperceptible to the naked eye. Thus, this paper formulated the VLC based system for indoor applications and evaluate its performance considering various parameters such as optical power distribution (OPD), signal to noise ratio (SNR) and channel delay spread (CDS). The observation of the OPD of a single LED transmitter and a single receiver along with 4 transmitters and receivers in a typical room has been considered. The other performance matrices such as SNR and CDS of VLC is also analyses and simulated using MATLAB software.
