A wireless communication device includes: a channel matrix estimating unit estimating a channel matrix including channel response elements between antennas; a phase error estimating unit estimating a phase error in a received signal on the basis of a decoding result of encoded and transmitted information symbols of a preamble of a received packet; and a waveform equalizing unit equalizing a waveform of data symbols of the received packet using the channel matrix. Original channel response elements are derived by removing an error of an estimated channel value due to the phase error estimated by the phase error estimating unit from the channel response elements of the channel matrix supplied from the channel matrix estimating unit, and the waveform equalizing unit equalizes the waveform of the data symbols using the channel matrix including the original channel response elements.
