    • A signal containing a frequency-domain channel estimation value is received and a time-domain channel estimation value is computed by way of DFT computations. An Mth DFT computation, with which the DFT computation begins, is determined according to the number of data, having been not replaced with ‘0’, out of the N pieces of data constituting the frequency-domain channel estimation value. A twiddle factor is generated for computing a datum to be input into the Mth DFT computation. A datum is generated to be input into the Mth DFT computation, by using the frequency-domain channel estimation value and the twiddle factor. The time-domain channel estimation value is computed by performing DFT computations in a range from the Mth DFT computation to the Pth DFT computation, where P=log2 N and N is the number of data consisting the frequency-domain channel estimation value.
