Orthogonal Frequency Division Multiplexing (OFDM) systems in modern high data rate wireless communication are a very useful because of its multi carrier modulation technique. But one of the major disadvantages in OFDM systems is Inter-Carrier Interference (ICI) which may be cause for Doppler shift due to relative motion between transmitter and receiver local oscillator frequencies. ICI problem become more complicated when multipath fading is present which results in power leakage among subcarriers, degrading the overall system performance.
