A correction coefficient calculating section 20 calculates a correction coefficient ² so as to obtain a noise power equivalent to detected path and adjacent path transmission channel estimation values. A noise power correcting section 21 calculates a corrected noise power ²N0. A weight calculating section 8 receives as its input a frequency-domain transmission channel estimation value H(f) being an output of an FFT section 7 and the noise power ²N0 corrected by the noise power correcting section 21 and calculates a weight of an equalization filter by MMSE. |
