Popis: An improved Nyquist pulse was presented.The proposed pulse waveform can significantly reduce the PAPR and keep the system BER invariant at the same time,but at the expense of a little spectrum loss.Simulation results show that the proposed shaping pulse can get better performance of PAPR compared to traditional raised cosine pulse and flipped-exponential pulse.It is an effective method with low complexity to reduced the PAPR of OFDM signal by pulse shapping with the proposed nyquist pulse.
