Bit Error Rate Analysis for Indoor Optical Wireless Communication System

For this paper, we use visible light spectrum (380–740 nm wavelength) for indoor optical wireless communication which is an emerging technology and new way for indoor communications. It uses the already built-in LED infrastructure which is being used for illumination, to transmit signals and photodiode for receiving signals. This paper contains BER analysis for indoor visible light communication for indoor communication. The system model consists of one LED and one photodiode which form a classic point-to-point indoor visible light communication system. The Lambertian emission-based channel model is used along with On–Off Keying modulation. The effect of various parameters on BER is studied and plotted.
