Modified PTS-based PAPR reduction for ACO-OFDM in visible light communications

Modified PTS-based PAPR reduction for ACO-OFDM in visible light communications
Modified PTS-based PAPR reduction for ACO-OFDM in visible light communications
In this letter, we propose a modified PTS-based PAPR reduction scheme for ACO-OFDM in VLC systems by exploiting the unoccupied subcarriers to transmit side information. A novel transmitter is presented to apply the PTS technique in ACO-OFDM VLC system without data throughput loss and an original power allocation method is also proposed to mitigate the power efficiency loss induced by the side information signals. Simulation results demonstrate that the proposed scheme achieves a significant PAPR reduction performance without data throughput loss as well as an improved BER performance when LED nonlinearity exists.

Abstract

In this letter, we propose a modified PTS-based PAPR reduction scheme for ACO-OFDM in VLC systems by exploiting the unoccupied subcarriers to transmit side information. A novel transmitter is presented to apply the PTS technique in ACO-OFDM VLC system without data throughput loss and an original power allocation method is also proposed to mitigate the power efficiency loss induced by the side information signals. Simulation results demonstrate that the proposed scheme achieves a significant PAPR reduction performance without data throughput loss as well as an improved BER performance when LED nonlinearity exists.
