Abstract
This paper investigates the performance of a two way decode and forward (DF) relayed Visible light communication (VLC) system with a backhaul solution. The visible light emitting diodes (LEDs) serve for downlink transmission and the infrared LEDs serve for the uplink transmission. In this paper two backhaul solutions are analyzed first being the traditional radio frequency (RF) and the other one being the free space optics (FSO). We derive the closed form expressions of signal to noise (SNR) statistics i.e. Cumulative Distribution Function (CDF) and Probability Density Function (PDF)). We further achieve the expressions for Average Bit Error Rate (ABER) and outage performance.
