Abstract
To reduce the peak-to-average power ratio (PAPR) of a complex-valued digital baseband signal, the signal is mixed to an intermediate frequency and its real components extracted, to generate an intermediate-frequency real-valued digital signal. The intermediate frequency is one-quarter of a sampling rate of the complex-valued digital baseband signal. The intermediate-frequency real-valued digital signal is clipped and down-converted by one-quarter of the sampling rate.
