OFDM

Hi All

Im new in this group. I want to say helo to all. I have now only one question " How can I use matLab to make OFDM model that considers the effect of:
1- AWGN (SNR with BER)
2- Fading.
and it can shows the amplitude spectrum of the received signal.


Many thanks to all

By running IFFT operation over the frequency domain symbol ? Isn't this obvious?

It is always in time domain, it has never been in frequency domain.
