WebIn this study, the PTS technique is employed to reduce the high PAPR value of an F-OFDM system. Then, this system is compared with the OFDM system. In addition, the other related parameters such as frequency localization, bit error rate (BER), and computational complexity are evaluated and analyzed for both systems with and without PTS. WebOrthogonal frequency division multiplexing (OFDM) technique has been widely used in visible light communications (VLC) system (VLC-OFDM). To minimize the performance degradation of VLC-OFDM system caused by high peak-to-average power ratio (PAPR), we propose a SFLAHC-PTS technique to reduce the PAPR of signal in this paper.
