A device for mitigating inter-carrier interference (ICI) includes a channel estimator, a channel calculator, an ICI estimator, a subtracter, and an equalizer. The channel estimator estimates a channel response from which the channel calculator calculates a basic component of a channel response and fluctuating components of the channel response. The ICI estimator multiplies the fluctuating components of the channel response by a frequency domain representation of the received signal, filters the result and estimates an ICI component of the received signal based on the output of the filter. The subtracter subtracts the ICI component from the frequency domain representation of the received signal. The equalizer equalizes an output signal of the subtracter based on the basic component of the channel response.
