Question Regarding PAPR-CCDF of OFDM

[andhrama]

Sir, In the paper 'End-to-End Learning of OFDM Waveforms with PAPR and ACLR Constraints', a PAPR-CCDF plot for the E2E system and Tone reserved OFDM (Fig. 5) has been shown as in the image uploaded. Can you please comment on how such a smooth plot is generated. moreover, as I understand the concept of CCDF, the CCDF represents the Probability that PAPR of the signal being greater than a certain value (plotted as x-axis), or in case of the paper, the |s(t)|^2. but as per the image, it looks like that for |s(t)|^2 to be greater than 0 db, the probability is NOT 100%. Shouldn't it hit CCDF = 1, at PAPR = 0dB. Otherwise, why is that the case? can you please answer?
Thank you so much!

Hi @andhrama,
