A NOMA scheme for visible light communications using a single carrier transmission

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 a low peak-to-average power ratio (PAPR), a good balance between the throughput and fairness, and a higher system capacity for a larger number of users. We show that the proosed scheme offers improved bit error rate performance compared to the orthogonal frequency domain multiplexing based VLC system.
