Hello,
I have already simulated and OFDM system over AWGN channel. Now, I need to apply
flat fading and frequency selective fading with Rayleigh distribution as my
channel effect.
I have tried it and my problem is that I do not know which kind of equalizer I
should use in order to remove the effect of fading.
Anyone has some idea? I would really appreciate it.
Sincerely,
Saina

There are a number of channel estimation algorithms available. The easiest
way would be to use a pilot symbol for channel estimation, and a simple zero
forcing equalizer for equalization.
Frequency domain equalization works well with OFDM making things simpler.
Hope this helps.
