The radio base station of the present invention detects desired sampling points, which are sampling points having reception levels higher than or equivalent to a predetermined threshold, to calculate a ratio of the desired sampling points to the entirety of sampling points contained in a desired bandwidth, the total number of sampling points being equivalent to the number of carriers in one cycle of the frequency band of the reception signal. Further, so as to calculate a gain to be applied in the amplification of signal level to a predetermined target level, the radio station uses as a gain a value obtained by dividing the target level by a product, the product being obtained by performing multiplication of an average value of levels of the signal components within the desired frequency band and an reciprocal of the ratio calculated.
