What is Ccdf in PAPR?
The CCDF or Pr[PAPR > PAPR0] denotes the probability of the signals having a PAPR greater than threshold PAPR0. The CCDF of PAPR performance of the proposed technique is investigated by 16 subcarriers OFDM- system as shown in Figure.
How to calculate CCDF?
CCDF Calculation
Normalize all samples to the RMS value in units of dB. Determine which x-axis bin each sample belongs in between 0 and 20 dB. Calculate the total number of samples that are greater than or equal to each x-axis bin and plot as a percent of the number of samples measured.
