Abstract: In a receiver of the present invention, a local oscillator frequency, used as a basis for a reception unit to demodulate a received signal, is generated by a local oscillator based on a reference frequency, which is generated by a voltage-controlled oscillator whose oscillation frequency is adjusted by a control voltage applied thereto. The control voltage is prescribed by a decoding unit which monitors a reception electric field intensity (RSSi) or an error rate in the reception unit. The control voltage is adjusted in a manner to increase the reception electric field intensity (RSSi) or reduce the error rate. When the local oscillator frequency experiences a large deviation and the signal cannot be received with good reception sensitivity, the decoding unit generates a control voltage in a manner so as to eliminate the deviation and applies the generated control voltage to the voltage-controlled oscillator for automatically adjusting the local oscillator frequency to a level having a reduced deviation.
