Grouped discrete Hartley transform precoding for low-complexity PAPR reduction in ACO-OFDM visible light communication systems

Abstract The high peak-to-average power ratio (PAPR) remains one of the major challenges affecting asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) systems used in visible light communication (VLC). Although transform precoding techniques such...
