Research on alleviating nonlinear problem by data feature extraction and fusion based on DFT-spread

EURASIP Journal on Advances in Signal Processing, 2023
Coherent optical orthogonal frequency division multiplexing (CO-OFDM) system is susceptible to nonlinear effects because of its intrinsic high peak-to-average ratio (PAPR). In this paper, two methods based on discrete Fourier transform spread (DFT-S) are
