A Visible Light Communication based predictive system for the height and location estimation of an obstacle

This paper presents a visible light communication (VLC) - based predictive system for estimating an obstacle's height and location in an indoor environment. Two types of indoor environments having one and four LED's respectively are considered for the simulation. In each of the above environments, the system is first simulated using an infinitely thin obstacle and then using an obstacle having a radius of 0.05m. Linear Regression is applied to the results to develop a predictive algorithm to obtain the location and height of an obstacle from the received power profile. Finally, the accuracy of the predictive system for each of the above scenarios is also measured.
