Outage Analysis of an Asymmetric dual hop PLC-VLC system for Indoor Broadcasting

Abstract

We propose and investigate the performance of a novel asymmetric dual hop relay based power line communication (PLC) and visible light communication (VLC) system for the purpose of indoor broadcasting. The PLC link experiences log-normal fading and additive noises. The PLC link is used as a back-haul link for the VLC downlink transmission system which serve multiple end users. The characteristics of the VLC links are dependent on the random position of the end users. Novel closed form expressions for the cumulative distribution function (CDF) of the end to end signal to noise ratio (SNR) of the proposed system is derived. Also, capitalising on these derived entities, the system's performance is evaluated in terms of the outage probability (OP) metric.
