Abstract: A wireless communication apparatus for receiving a packet formed of a signal modulated by OFDM includes the following elements. A band-pass filter extracts an OFDM signal of a desired band. A low-noise amplifier having a gain controlled according to a received-signal intensity amplifies the desired OFDM signal. A frequency converter down-converts the amplified OFDM signal into a baseband signal. An analog-digital converter converts the baseband signal into a digital signal. A first high-pass filter removes a DC offset from the baseband signal corresponding to a predetermined preamble portion of the packet. A frequency-offset estimator estimates a frequency offset from the sample signals constituting the baseband signal from which the DC offset has been removed by the first high-pass filter. A frequency-offset corrector removes the estimated frequency offset from the baseband signal.
