N2 - DFT-s-OFDM/Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (OFDM) is a waveform adopted in the fourth and fifth generation of the mobile communication standards, aiming to combine the merits of Cyclic Prefix (CP) OFDM with a low Peak-to-Average-Power Ratio (PAPR). Due to the growing interest in geometric and probabilistic shaping of the signal constellation, it is important to study the impact of shaping on the power distribution of the corresponding signal. In this work, exact and approximate analytic expressions are derived for the Instantaneous-to-Average-Power Ratio (IAPR) and PAPR of this waveform, respectively. These expressions can be used for understanding and comparison of the effects of geometric and probabilistic shaping techniques on the power distribution of the transmitted signal.
