Abstract
A wireless communication system includes: a measurement unit that measures a signal level of an analog signal corresponding to a received radio signal; a first output unit that amplifies an amplitude of the analog signal and extracts an analog signal with a desired frequency band from the analog signal with the amplified amplitude; a second output unit that extracts an analog signal with a desired frequency band from the analog signal and amplifies an amplitude of the extracted analog signal; and a switching control unit that inputs the analog signal corresponding to the received radio signal to the first output unit when the signal level of the analog signal other than the desired frequency band is less than a threshold, and inputs the analog signal corresponding to the received radio signal to the second output unit when the signal level of the analog signal other than the desired frequency band is equal to or greater than the threshold.
