Patent ID: 7343143

Claim:
A radio receiver comprising: an adjacent station detection unit for detecting the existence of an adjacent station transmitting a broadcast signal at a frequency adjacent to a predetermined receive frequency; a broadcast signal reception unit for receiving a broadcast signal at the receive frequency and reproducing a content of the broadcast signal; a receive state detection unit for detecting a receive state of a broadcast signal to be received; an operation state setting unit for setting an operation state of said broadcast signal reception unit based on the receive state detected by said receive state detection unit and the detection result by said adjacent station detection unit, wherein said operation state is an input/output characteristic comprising one or more of a channel separation characteristic, a blend characteristic, a high-cut characteristic, and a soft mute characteristic, and the set operation state when an adjacent station is detected is different than the set operation state when no adjacent station is detected, and wherein the receive state detected by said receive state detection unit is a receive electric field strength of the broadcast signal.
