Visible light communication is a hot topic of wireless communication area which has drawn more attention to be researched. Dft-s ofdm is a main modulation method used in long term evolution (lte) in wireless communication, which is able to reduce the nonlinear limitation in client amplifier. Modulating directly by transmitter led in vlc will cause a strong linear effect which is harmful. As a result, this paper is aimed to do a research to study the anti-linear ability of dft-s ofdm. The study shows that dft-s ofdm is helpful in reducing linear effect and papr. It also shows the simulation and experiment results to make sure the system can work safely and precisely in a certain situation. We make a conclusion that less number of subcarriers can help to lower papr and bit error ratio (ber).
