Abstract
According to one embodiment, a wireless communication device which comprises an automatic frequency controller configured to detect a radio frequency shift amount between a transmitting side and a receiving side, comprises a controller, a first weight multiplier, and an error correction decoder. The controller is configured to designate subcarrier that suffers interference caused by a DC component based on the radio frequency shift amount detected by the automatic frequency controller. The first weight multiplier is 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. The error correction decoder is configured to perform error correction of the demodulated signals multiplied by the weighting coefficient by the first weight multiplier. The controller sets the weighting coefficient to be multiplied by the first weight multiplier based on the radio frequency shift amount.
