Abstract

This paper uses Discrete Fourier Transform spread spectrum (DFT-Spread) technology to extend the frequency domain of ortho-subcarriers in orthogonal frequency division multiplexing (OFDM), which can effectively reduce the PAPR of coherent optical orthogonal frequency division multiplexing CO-OFDM system. Based on DFT-Spread-COOFDM system theory and simulation analysis, shows that this method not only can effectively reduce the PAPR of coherent detection system CO-OFDM signal, at the same time, compared with the traditional OFDM system, analysis it only adds to the complexity of a Fourier transform (FFT), the amount of calculation than selective mapping traditional (SLM), partial transmit sequence (PLS) technology to reduce PAPR algorithm has lower complexity.
