摘要：
In this paper, we proposed a novel peak to average power ratio (PAPR) reduction scheme for the DC-biased optical orthogonal frequency division multiplexing visible light communications (DCO-OFDM) systems. We implement the Gaussian matrix multiplication method to reduce the high PAPR of the DCO-OFDM system at the transmitter and use the back propagation (BP) algorithm to recover the original OFDM frame at the receiver. The simulation results show that the proposed scheme can achieve a PAPR(0) reduction by about 3 dB for 128-subcarrier DCO-OFDM systems, and a nearly identical bit error rate (BER) performance to the ideal OFDM system with no distortion.
