Hi Aya,
How are you?
Aya, I'm a master degree student in telecommunication field, my interest is related to the equalization, channel estimation issues.
My master thesis related to the OFDM, I want to ask about the zero padding, did you mean that this zero padding will be the in-active subcarriers?
Further I have a big trouble in the turbo erqualization, if you have any knoweldge in that would you help me please?
Best Regards, and Thank you very much in advance.

Aya,
you mentioned that you have to add the noise after the ifft process, but I don't think that this is correct, the noise addition must be in the time domain, then the IFFT operation is applied.
Best Regards.
