A method for estimating channels of an OFDM signal. The method comprises the steps of deriving responses of pilot channels, deriving responses of first data channels by time and frequency domain combined linear interpolation among the responses of the pilot channels, deriving each response of boundary channels by frequency domain linear interpolation between the responses of the nearest pilot and first data channels, and deriving responses of second data channels by frequency domain extrapolation using the responses of the pilot and first data channels.
