Abstract
A radio receiver (FM radio receiver) has an amplitude detecting section () for detecting the amplitude level of a received radio wave; a multipath occurrence state detecting section () for monitoring the amplitude level, and for detecting the degree of a multipath occurrence state; a multipath occurrence state deciding section () for deciding the operation limiting level of the amplitude correction according to the degree of the multipath occurrence state; a receiving condition deciding section () for deciding receiving conditions of the radio wave; and a limiting level deciding section () for adjusting the operation limiting level of the amplitude correction output from the multipath occurrence state deciding section () according to a receiving condition decision result output from the receiving condition deciding section (), and suppresses the multipath noise by imposing operation limitations on the amplitude correction of the FM demodulator
