Radio communication device and frequency error measurement method
A radio communication device includes a transmission unit that performs a radio transmission process on a baseband signal in which transmission data is included and that transmits a signal in which the baseband signal is superimposed on a carrier wave; a feedback unit that feeds back the signal transmitted by the transmission unit; a detecting unit that detects a carrier wave component by removing a component corresponding to the baseband signal from a feedback signal that is fed back by the feedback unit; a counting unit that counts the pulses of the carrier wave component detected by the detecting unit; and a calculating unit that calculates a frequency error of the carrier wave by using a count value obtained by the counting unit.
