DOI: 10.1016/j.ijleo.2019.02.070
Abstract: Abstract We propose a non-orthogonal multiple access (NOMA) scheme for visible light communications (VLC) based on single carrier (SC) transmission and frequency-domain successive interference cancellation. The scheme can achieve low peak-to-average power ratio (PAPR), a… read more here.

DOI: 10.1109/twc.2018.2864215
Abstract: The notion of non-orthogonal multiple access (NOMA) for 5G essentially relies on the availability of the channel state information at the transmitter (CSIT). Such knowledge is used to judiciously allocate power among users to make… read more here.
