Abstract

In this paper, we investigate the performance of spectrally and energy efficient orthogonal frequency-division multiplexing (SEE-OFDM) based visible light communications (VLC) systems. We propose to apply non-orthogonal multiple access (NOMA) for the downlink in SEE- OFDM based VLC network. Moreover, we provide a novel approach in decoding the composite NOMA signal. Next, based on the considered channel conditions, we analyze the impact of power-allocating coefficients on the bit-error rate (BER) performance. Finally, satisfying the target BER, we estimate the data rate regions achievable by the receivers under the derived system parameters and then compare the results with the ones obtainable for orthogonal multiple access.
