The present invention provides an equalizing device, a receiving device and an equalizing method. In an environment that a receiver moves, estimation precision reduction for delay distribution can be restrained. The equalizing device (12) is provided with the following components: a correlation calculating part (21) which acquires a correlation sequence between a known signal sequence and a received signal (Rs); an arrived wave detecting part (23) which detects the position of a plurality of correlation peak values that respectively correspond with a plurality of arrived waves according to the correlation sequence; a variation amount detecting part (24) which detects time variation of the plurality of correlation peak values; a smoothing part (26) which performs smoothing wave filtering on the correlation sequence in a code element direction for generating eliminated delay distribution; and an equalizing processing part (13) which corrects distortion of the received signal (Re) according to the eliminated delay distribution. The smoothing part (26) changes smoothing wave filtering characteristic according to time variation of the correlation peak values. |
