In this paper,considering the limited modulation bandwidth of LED in visible light communication (VLC) and the nonlinear effect of the LED,the technology combining the discrete Fourier transf orm (DFT)-spread technology with adaptively modulated orthogonal frequency divi sion multiplexing (OFDM) technology,adaptive DFT-spread-OFDM is proposed in this paper for getti ng both relatively high rate and reliable communication.Through the simulation and the experiment,a comprehensi ve comparison is made among adaptive DFT-spread-OFDM scheme,conventional DFT-spread-OFDM scheme and c onventional adaptively modulated OFDM scheme.In the simulation,the peak-to-average power ratio (PAPR) complementary cumulative dist ribution functions (CCDFs) of different system schemes are measured.In the exper iment,the bit error ratio (BER) performances of different system schemes are measured for a further comparison.In addition,the comparisons of the system complexity and the system communication r ate are made among different system schemes.The results indicate that adaptive DFT-spread-OFDM scheme can achieve higher rate compared with the conventional DFT-spread-OFDM scheme,and can achieve better PAPR performance compared with conventional adaptively modulated OFDM scheme.It has b een verified that the proposed adaptive DFT-spread-OFDM scheme can achieve good comprehensive perfor mance.
