摘要:
A receiving apparatus includes: a demodulating unit which demodulates an IF signal obtained by subjecting a received RF signal to frequency conversion; a detecting unit which detects a carrier wave frequency error contained in the IF signal; a frequency control unit which sets an initial value of a frequency in the demodulation process by the demodulating unit and for correcting a frequency error of a frequency used for the demodulation process by the demodulating unit based on the carrier wave frequency error detected by the detecting unit; and a control unit which controls a setting of an initial value of a frequency in the demodulation process by the demodulating unit by means of the frequency control unit after a receiving channel is switched, based on the carrier wave frequency error before a receiving channel is switched, the error being detected by the detecting unit, when a receiving channel is switched.
