Abstract(in English) In this paper, we propose IDMC (Interference Division Multipath Canceler) for OFDM. In OFDM system, ISI (Inter-Symbol Interference) and ICI (Inter-Carrier Interference) caused by symbol timing asynchronization or large multipath delay longer than the GI (Gurad Interval) cause severe degradation of receiving performance. This proposed scheme reduces the influence of both ISI and ICI by making the replica of them on the data carrier by interpolating them on the pilot carrier and subtracting it from the received signal. For multipath longer than the range of interpolation, it improves its recieving performance by adjusting symbol timing to divide the interference to both ends of FFT window. Simulation results prove that the proposed scheme is useful for reduction the influence of multipath with large delay longer than the GI
