I add AWGN noise in the transmission, then introduce FO, lastly, estimate the FO but it fluctuates very much (have negative and positive FO). I sum all of them and divide to take averaging result but not accurate. How to improve the accuracy? Hi Kirshna,

I want to add the Sampling Frequency Offset (SFO) in my OFDM system simulation. I believe that I should do that in time domain, but dont know exactly how??? I apperciate you help Regards Hi Kirshna,
