N2 - Visible light communications (VLC) is a new topic within the optical wireless communications (OWC), which has attracted the interest of researchers in recent years. Investigating non-line of sight VLC systems in terms of the rms delay spread, signal to noise ratio (SNR), bit error rate (BER), etc. is essential to fully appreciate the implication of this emerging technology. In previous works, the effect of changing the transmitter configuration on the distribution of illumination, the channel rms delay spread or the output power has been investigated. In this article, we investigate the SNR at the receiver by changing the semi angle at half power, field of view (FOV) of the transmitter and receiver as well as the array size and positions of the transmitters. We show that the distribution of SNR highly depends on the number of transmitters. We also show that for some specific profiles of the receiver the convergence of SNR depends on the transmitter topology.
