Frequency synchronization is vital issue in execution of OFDM system. In this paper, the authors proposed a technique to estimate and compensate CFO in frequency domain. Estimation is based on comb-type pilot sequence, which can measure phase rotation of received signal pass through fading channel. Performance of proposed scheme is evaluated on basis of MSE and BER. CFO estimation can be computed by pilot, phase information obtained at receiver side. It is estimated at receiver by fine CFO estimation.
