Error Probability Analysis of Hybrid VLC/PLC/VLC Communication System with DF Relays

Abstract

In this paper, we discuss a hybrid communication system for transmitting information between end users which are located indoors. The transmission is conveyed through visible light communication (VLC) links and a power line communication (PLC) link connected via decode-and-forward relays. The performance of this three-hop hybrid system is analysed in term of average bit error rate (BER) and the impact of VLC and PLC channel parameters is investigated. In more details, the influence of light emitting diode lamp position (height, radiation angle), influence of the average signal-to-noise ratios from all links and fading presence on the average BER is considered.
