Abstract— Orthogonal frequency division multiplexing (OFDM) is very sensitive to frequency offset caused by Doppler frequency drift or frequency drift between transmitter and receiver oscillator. This leads to a loss in the orthogonality between sub-carriers and results in inter-carrier-interference (ICI). In this paper we proposed an efficient ICI self-cancellation scheme to reduce ICI in OFDM system and its performance is compared with existing methods of self-cancellation in terms of carrier-to-interference ratio (CIR) and bit-error rate (BER). Simulation result shows that the proposed scheme outperforms the existing schemes.

For broadband wireless mobile communication systems the orthogonal frequency division multiplexing (OFDM) is a suitable modulation scheme. The frequency offset between transmitter and receiver local oscillator is main drawback of OFDM systems, which causes intercarrier interference (ICI) in the subcarriers of the OFDM system. This ICI degrades the bit error rate (BER) performance of the system....
