Abstract
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 (PAPR) of the transmitted signal. The technique causes no increase in out-of-band power. Significant PAPR reduction can be achieved with only moderate levels of clipping noise
