Investigation on overlapping interference on VLC networks consisting of multiple LEDs

Visible light communication (VLC) has become an alternative candidate in next-generation indoor wireless local area network. However, it is a great challenge for a receiver to obtain the signals from multiple LED sources that transmit different information. In this paper, we explore the BER degradat...
