Thank you very much ,I do get the same results! I am so happy now.
I owe all to your helpful website,Thank again!

On the topic of the effect of oversampling,you can have a look at the help doc of matlab,there is a explanation.

Or you can refer to my blog ,I paste the ‘explanation’ on that. since I am from Chinese,you can ignore those words,just have a look at the last picture.

@Michael: Yes, BER vs Eb/N0 should be the same

@Michael: Mmm… for the oversampling affecting the SNR, can you point to a specific example?

one more question: I think if we use other types of modulation(16-qam,qpsk,etc) , then on the condition of AWGN channel, the BER-EbN0 will be the same no matter whether we adopt the OFDM technique. ~~~ is that right?

then we do obtain that the simulation results are the same as the theory ber??
