Radio receiver for suppressing low-frequency signal attenuation characteristics and suppression method thereof

摘要

The present invention is intended to realize a radio receiver for more effectively suppressing low frequency signal attenuation characteristics in an analog frequency modulation type wireless communication system. In order to achieve these objects, a radio receiver according to the present invention comprises a first frequency converter for mixing an RF signal received by the receiver with a predetermined local oscillation signal to output an intermediate frequency signal, A modulator for modulating the oscillation signal using a voice signal transmitted from the transmitter and applying the modulated signal to the first frequency converter; and a modulator for converting the intermediate frequency signal output from the down-And a demodulator for demodulating a baseband signal output from the second frequency converter.
