<p>In the present application, channel estimation values calculated based on pilot symbols can be used for channel compensation of data symbols in an OFDM receiver, even in cases where FFT extract position differs for each frame. The OFDM receiver comprises a circuit (102) which calculates the amount of phase rotation that is generated by the difference in timing at which the individual symbols are extract as objects of a fast Fourier transform when the fast Fourier transform processing is performed by a fast Fourier transform circuit (10), and further a circuit (105-107) which corrects the amount of phase rotation of the channel estimation value determined by a channel estimating circuit (101).</p> |
