rayleigh flat fading vs frequency selective fading ofdm

[anta]

Hi all!
I have simulated a rayleigh flat fading channel (ofdm) and a frequency selective exponential channel in which every tap follows rayleigh distribution,thus every tap 'sees' a flat rayleigh channel (due to ofdm)...is this right? However i wonder what the plot would be? The plot (BER vs SNR) is almost the same for both cases?
This is right,isn't it?

Thank you in advance

doesn't anybodt know?

I have used 30 real taps

wow... 30 taps is too much, are you sure your modem is designed properly?

How much is the length of the CP and the number of subcarriers

The length of cp is 32 thus no ISI and the num of subcarriers is 16384
