The concept of location-based equalization for indoor visible light communications

Abstract

In this paper, we propose a novel concept of the location-based equalization scheme for indoor visible light communication (VLC) systems. For the first time, indoor VLC can become an indoor visible light positioning based service. Numerical results prove that the proposed scheme is a simple and effective solution to counteract the inter-symbol interference induced by the indoor VLC dispersive channel. For example, for a 100 Mbps transmission link, the proportion of the indoor area with a bit error rate of less than 10−6 can be increased from around 70.4% to 92.3% by adopting the proposed scheme.
