A reception quality in a radio base station eNB is estimated with a high accuracy by using a reference signal. The radio base station eNB according to the present invention includes signal power estimation units 11B, 12B, and 13B configured to calculate a correlation value Z(a) between a predetermined number N of continuous samples “a” to “a+N−1” in sequences constituting a transmitted signal XL(n) of a predetermined signal transmitted by a mobile station UE#L and a predetermined number N of continuous samples “a” to “a+N−1” in sequences constituting a received signal r(n) of the predetermined signal in the radio base station eNB, and calculate received power Spower of the predetermined signal using the correlation value Z(a).
A radio base station, which is configured to receive a predetermined signal formed using a predetermined sequence from a mobile station, the predetermined sequence having a constant amplitude on a time domain and a frequency domain and a self-correlation of 0, comprising:
