a pilot signal extractor configured to extract a pilot signal from a received orthogonal frequency division multiplexing (OFDM) signal;
an estimator configured to estimate a characteristic of a channel of the OFDM signal for the pilot signal and interpolate a channel characteristic in a time direction to thereby obtain a channel characteristic of every predetermined number of subcarriers;
an interpolator configured to carry out filtering of the channel characteristic of every predetermined number of subcarriers by an interpolation filter having a first band for interpolating a channel characteristic in a frequency direction to thereby obtain a first all-subcarrier channel characteristic, and carry out filtering of the channel characteristic of every predetermined number of subcarriers by an interpolation filter having a second band wider than the first band for interpolating a channel characteristic in the frequency direction to thereby obtain a second all-subcarrier channel characteristic;
a distortion corrector configured to correct distortion of the OFDM signal by using the first all-subcarrier channel characteristic and correct distortion of the OFDM signal by using the second all-subcarrier channel characteristic;
a calculator configured to calculate quality of each of the OFDM signals whose distortion has been corrected; and
a determiner configured to determine whether or not a channel environment is a single path environment or a near delay path environment in which all paths are allowed to be included in a passband of an interpolation filter having the first band, based on quality of a first distortion-corrected signal that is the OFDM signal whose distortion has been corrected by using the first all-subcarrier channel characteristic and quality of a second distortion-corrected signal that is the OFDM signal whose distortion has been corrected by using the second all-subcarrier channel characteristic.
