ABSTRACT:
The value of a pilot signal extracted from the received signal is divided by the known value (sm,n) of the pilot signal to obtain a channel characteristic value (3), changes in the timing of the Fourier transform are detected (5), and on the basis of the detected result, interpolated data are generated (4) by selection or interpolation in the time direction, using the channel characteristic values as the original data. The decoding error rate after equalization when the timing of the Fourier transform changes is lowered, and receiving performance is improved.
