<p>A radio receiver (FM radio receiver) comprises an amplitude detecting section (13) for detecting the amplitude level of received air, a multipath occurrence status detecting section (14) for monitoring the amplitude level to detect the degree of multipath occurrence status, a multipath occurrence status determining section (15) for determining the operation restriction level of the amplitude correction on the basis of the degree of the multipath occurrence status, a reception status determining section (20) for determining the reception status of the air, and a restriction level determining section (21) for adjusting the operation restriction level of the amplitude correction outputted by the multipath occurrence status determining section (15) according to the result of the determination of the reception status outputted from the reception status determining section (20), and puts an operation restriction on the amplitude correction of an FM demodulator (9) to perform the suppression of a multipath noise.</p> |
