  Wavelength division multiplexing (WDM) and non-orthogonal multiple access
(NOMA) are employed in a visible light communication (VLC) system to increase
the capacity of the system. The system is evaluated using two different
scenarios focusing on power and data rate, where the first scenario is based on
fair power allocation while the second scenario provides equal power
allocation. Data rate variation is evaluated as a function of the users
positioning and mobility. In both scenarios the proposed NOMA-WDM system
achieved higher data rate NOMA system.
