OFDM system suffers from inter-carrier interference due to frequency offset produced by the movement of terminals. Several schemes have been proposed to mitigate this type of interference. In this paper, an unscented Kalman filter (UKF) based methodology is addressed to estimate the carrier frequency offset (CFO).We have compared the BER performance of UKF with other schemes and also analyzed the convergence as well as accuracy behavior between UKF and EKF. The simulation result shows that comparing to conventional non-iterative methods, UKF and EKF have higher accuracy and efficiency. Furthermore, UKF surpasses EKF in convergence rate and consistency. |
