Performance Analysis of Multi-Input Single-Output Links in Dense VLC Networks

Dense Visible Light Communication (VLC) networks may offer a cost-effective solution to meet the growing demand for wireless data as legacy radio frequency (RF) bands are getting crowded. In this paper, we present a detailed analytical model and link performance analysis for dense multi-element VLC networks in the presence of spatial and temporal optical interference caused by multiple transmitters broadcasting data over a Multi-Input Single-Output VLC channel. In dense VLC networks, we investigate how the spatial interference caused by cross-talk degrades the link performance and calculate the Bit Error Rate of the link to determine the maximum data rate capacity of the channel for reliable communications.
