ABSTRACT:
There is provided a radio receiver which can set a proper receive state regardless of the existence of an adjacent station. If an adjacent station detection circuit detects an IBOC station having a carrier frequency adjacent to a receive frequency, a control unit transmits instructions to a stereo demodulation circuit, a soft mute circuit, and the like to change control states of input/output characteristics such as a channel separation characteristic, a blend characteristic, a high-cut characteristic, and a soft mute characteristic. The control unit also transmits instructions to a multi-path detection circuit and an adjacent interference detection circuit to change thresholds used for detecting multi-path interference and adjacent interference.
