Abstract

Abstract:

In order to solve the peak-to-power ratio (PAPR) problem in asymmetric shear orthogonal frequency division multiplexing (ACO-OFDM) visible light communication (VLC) systems, using the idea of partial transmit sequence (PTS) method, and combining the discrete particle swarm optimization (DPSO) algorithm, an improved PTS peak-to-average ratio suppression method—DPSO-PTS method is proposed. The DPSO algorithm is used to optimize the weighted phase factors, select the best combination of phase factors to effectively control the range of PAPR, and sum the subblocks of multiplicative weighted information, so as to select a group of signals corresponding to the minimum PAPR for transmission.The simulation results show that when the complementary cumulative distribution function (CCDF) is 10^-4, the PAPR of DPSO-PTS method is reduced by about 4 dB, and the complexity and bit error rate (BER) performance of DPSO-PTS method are also improved effectively compared with the traditional PTS method.

Key words: visible light communication (VLC), asymmetric-clipped orthogonal frequency division multiplexing (ACO-OFDM), peak-to-average power ratio (PAPP), discrete particle swarm optimization-partial transmit sequence (DPSO-PTS) method
