A characteristic of orthogonal frequency-division multiplexing (OFDM) and other digital modulation schemes is high crest factor values or peak-to-average-power ratios (PAPR). High PAPR signals can strain amplifiers, leading to challenges such as waveform clipping, nonlinearities, and increased bit errors. Since crest factor is a single numerical value, the complementary cumulative distribution function (CCDF) can be used to provide a more comprehensive view of signal behavior.
