Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) is an exceptional case of Frequency Division Multiplexing. The dilemma of OFDM is its sensitivity to frequency offset between the transmitted and received carrier frequencies. This frequency offset establishes Inter-Carrier Interference (ICI) Cancellation in the OFDM symbol. ICI reduction methods have been had by OFDM. This research considers three ICI self-cancellation (SC), maximum likelihood (ML) estimation, and extended Kalman filter (EKF) method. These three methods are compared in terms of bit error rate performance, bandwidth efficiency, and computational complexity. For high values of the frequency offset and for higher order modulation schemes, the SC method does not as well as the ML and EKF methods. Simulation results using MATLAB software.

Keywords :
