%X This paper proposes a novel channel estimation method for wireless Orthogonal Frequency Division Multiplexing (OFDM) systems. The method can significantly reduce the Inter-Carrier Interference (ICI) and additive white Gaussian noise by processing the received pilots both in multipath spread domain and Doppler spread domain. Furthermore, the method is adaptive in the sense that the cutoff frequency of the filter in the Doppler spread domain is designed dynamically to match the Signal-to-Noise Ratio (SNR). Computer simulation results demonstrate that the proposed method performs well at various Doppler frequency shifts.
