Performance Analysis of 200 Mb/s Indoor Visible Light Communication System Using Composite White Light Source

摘要

This paper describes an optical wireless communication (OWC) system that uses the RGB Light Emitting Diode (LED) for the generation of composite white light. We investigate and compare the performance of this indoor visible light communication (VLC) system in terms of bit error rate (BER) and quality factor for both non-return to zero (NRZ) and return to zero (RZ) on-off keying (OOK) modulation technique. A data rate of 200 Mb/s is achieved successfully over the 2.15 m of indoor LOS (Line of sight) channel under the presence of ambient light source and background noises in the system by optimizing the system parameters.
