Coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems have inferior nonlinear performance due to their high peak to average power ratio (PAPR) characteristics. In order to mitigate fiber nonlinearities for the CO-OFDM systems, we propose a novel discrete Fourier transform (DFT)-precoded coherent optical OFDM combined with a Hermitian symmetry (DFT-precoded HS CO-OFDM) system, which is a combination of the DFT-spread OFDM and the Hermitian symmetry of the DFT.
