摘要：

It is shown that repeated clipping and frequency domain filtering of an orthogonal frequency division multiplexing (OFDM) signal can significantly reduce the peak-to-average power ratio (PAP;) of the transmitted signal. The technique causes no increase in out-of-band power. Significant PAPR reduction can be achieved kith only moderate levels of clipping noise.
