Enhancing PAPR performance in optical-waveform for beyond 5G based VLC applications

Abstract Sixth-generation (6G) optical wireless links require high spectral efficiency at low energy cost, but the high peak-to-average power ratio (PAPR) of direct-current-biased optical orthogonal frequency division multiplexing (DCO-OFDM) forces large LED back-off, causes nonlinear distortion and clipping noise, and...

Signal detection in optical NOMA waveforms for VLC-based satellite systems using higher-order modulation

Abstract Visible-light communication (VLC) and free-space optical wireless communication offer high-frequency platforms for high-rate satellite links, while nonorthogonal multiple access (NOMA) enables multiple users to share the same optical resource. This paper investigates signal detection in a two-user optical NOMA...
