Abstract
A correction coefficient calculating sectioncalculates a correction coefficient β so as to obtain a noise power equivalent to detected path and adjacent path transmission channel estimation values. A noise power correcting sectioncalculates a corrected noise power βN. A weight calculating sectionreceives as its input a frequency-domain transmission channel estimation value H(f) being an output of an FFT sectionand the noise power βNcorrected by the noise power correcting sectionand calculates a weight of an equalization filter by MMSE.
