I wrote my code OFDM system, now I want to calculate PAPR of my OFDM system for kk = 1:nsym
Code dot - [expand]
1
2
3
4
5
6

peakpwer_ofdm(kk) = max(abs(ser_data(nsym,:)).^2);
% average power
 averagepower_ofdm(kk) = mean(abs(ser_data(nsym,:)).^2) ;
% PAPR
 PAPR_ofdm(kk) = peakpwer_ofdm/averagepower_ofdm ;
end

I use this code for PAPR calculation, Is it right ?
and why we plot CCDF vs PAPR? can anybody help me.
Best Regards
Kashif
