Hybrid C&C-DMA Scheme for Multi-User Access in Large-Scale VLC Network

Abstract

We propose a multi-user access scheme based on Color-code division multiple access (C&C-DMA) in VLC network. The experiment shows BERs of four users under one color channel are below 3.8 × 10∼3 when total data rate is 32Mbps by adopting conversed Walsh code and RGB LED.
