摘要

One of drawbacks of orthogonal frequency division multiplexing (OFDM) is the high peak-to-average power ratio (PAPR). A novel technique based on Nyquist pulse shaping is proposed for PAPR reduction. The method is based on a proper selection of the Nyquist pulses for shaping the different subcarriers of the OFDM modulation scheme. The maximum PAPR and the used pulse shaping waveform is derived and proved. It is shown by computer simulation that the proposed technique can achieve significant improvement in PAPR reduction in OFDM system. Its implementation complexity is much low in comparison to the previous published methods. Thus pulse shaping technique can be used not only to shape the spectrum of the transmitted signal but also to reduce its PAPR.
