Similar to the rest of comments. Could you provide me with the data file to help better understand the scripts?
thanks in advance,

Would u share the Signal_OFDM.mat file? Pls send it to gdpuly@qq.com. Thx U very much.

In the second curve ('Signal after PA without pre-distortion'), you made a mistake by repeating the following command:
hpsd = psd(hp, uPD, hpopts, 'centerdc', true, 'NFFT', lengthFFT);
I think you have to modify it as follows:
hpsd = psd(hp, uPA, hpopts, 'centerdc', true, 'NFFT', lengthFFT);

So great code. So great experiment. Could you provide the Signal_OFDM.mat to me. Let me have a see the whole link running.
Much thanks for sending it to my mail: bennie.xiang@gmail.com

hello sir , you code is very good but i can't run it beacause i don't have data (PA MODEL).
if you can send me the data in my mail: salisen13400@gmail.com
many thanks sir ........

HI, your code of DPD is goooood for me to learn...But i can not run it without the data of Signal_OFDM.mat?(I have tried to create it in many ways,but it can not get your result shown as figure)...I wonder if you can send it to me..my email( rjj000@126.com)...Many thanks...
