Claim:
1. A wireless receiver comprising: an RSSI generation circuit that obtains RSSI output corresponding to a carrier strength level of a received RF signal; a lookup table from which a threshold value corresponding to temperature information from a temperature sensor is read based on the temperature information; a comparison circuit that generates comparison output when the RSSI output is below the threshold value read from the lookup table or a value based on the threshold value, wherein the threshold value or the value based on the threshold value is one input, and the RSSI output from the RSSI generation circuit is the other input; and a muting circuit that closes a signal line of an audio signal demodulated from the RF signal, and cuts off output of the audio signal, based on the comparison output from the comparison circuit, wherein an inclination of the RSSI output relative to temperature and an inclination of the threshold value corresponding to the temperature information of the lookup table are equal to each other.
