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 good balance between throughput and fairness, and a higher system capacity for a larger number of users. We show by experiment that SC with a lower PAPR offers improved bit error rate (BER) performance compared with the orthogonal frequency division multiplexing.
