2018 arXiv   pre-print
The evolving explosion in high data rate services and applications will soon require the use of untapped, abundant unregulated spectrum of the visible light for communications to adequately meet the demands  ...  Visible light communication (VLC) has emerged as a great potential solution, either in replacement of, or complement to, existing RF networks, to support the projected traffic demands.  ...  For instance, for two users served by the same base station (BS), and using the same OFDM subcarriers, the BS assigns a high power to the user with poor channel and a low power for the user with a better  ...
