【Abstract】 Phase sequences with a special structure were designed and, thank to the special structure, the PAPR of the OFDM signal could be reduced directly in the time domain by employing the DFT property of the time domain circular convolution. The simulation results verify the effectiveness of the proposed method.更多还原
