Abstract

In recent years, the rapid growth of visible light communications (VLC) is driven the interest into new applications of this technology. While single-user VLC systems are widely studied in the literature, less attention is given to multiuser scenarios which are likely to be deployed. Thus, this paper studies a new low-complexity multiuser structure for indoor VLC systems using RGB channels. In this scheme, a time-based approach is employed to separate the users' signals which is combined with a three-dimensional signal constellation design to enhance the throughput on each user. The uncomplicated architecture of this multiuser system proves to be effective and appealing for low-cost implementations such as wireless sensor networks. Numerical simulations are carried out to evaluate the performance of the proposed scheme.
