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...
