Abstract OFDM system is very sensitive to time-varying channel, which may cause inter-carrier interference. In this paper, a layered inter-carrier interference cancellation scheme is proposed for time-varying channel, with detailed analysis of inter-carrier interference in frequency domain. The scheme proposed in this paper can compensate for the ICI terms that significantly affect the bit-error rate of the system. Simulation result is also given to show the performance this new scheme achieved.
