Patent ID: 8649452

Claim:
A wireless communication device which comprises an automatic frequency controller configured to receive a signal OFDM-modulated using subcarriers, and detect a radio frequency shift amount between a transmitting side and a receiving side, comprising: a controller configured to designate subcarrier that suffers interference caused by a DC component based on the radio frequency shift amount between the transmitting side and the receiving side which is detected by the automatic frequency controller; a first weight multiplier configured to multiply amplitude values of demodulated signals of signals carried by the subcarriers designated by the controller by a weighting coefficient in a range from 0 to 1; and an error correction decoder configured to perform error correction of the demodulated signals multiplied by the weighting coefficient by the first weight multiplier, wherein the controller sets the weighting coefficient to be multiplied by the first weight multiplier based on the radio frequency shift amount between the transmitting side and the receiving side.
