    OFDM modulated millimeter wave (mm-wave) at 60GHz. In order to improve transmission of this system, the discrete Fourier\ntransform spread (DFT-Spread) technology and the averaging of the channel frequency response (H-averaging) technology are\napplied. The DFT-Spread technology helps to reduce the peak-to-average power ratio (PAPR) of the OFDM signal, and the Haveraging\ntechnology helps to optimize channel estimation.This is the first time that the two kinds of technologywere used together\nin this reverse modulation system. According to the simulation, the 22Gbit/s 16QAM-OFDM at 60GHz can be generated and\ntransmitted for 90km fiber transmission under the soft decision forward error correction (SD-FEC) threshold 3.8Ã?10-3.The results\nshow that the two jointed DSP algorithms can improve the reverse modulation system transmission performance obviously
