Peak-to-average power ratio distribution analysis of single-carrier FDMA signals

This paper investigates the distribution of the peak-to-average power ratio (PAPR) of single-carrier frequency-division multiple-access (SC-FDMA) signals. An analytical approach that can numerically calculate its approximate distribution is presented. It is shown that the simulation and analytical results match in the dynamic range region of practical interest. We also compare the SC-FDMA with the corresponding orthogonal frequency-division multiplexing (OFDM) employing clipping and filtering in terms of PAPR and resulting average mutual information.
