Patent ID: 8379763

Claim:
A wireless communication device for performing a receiving operation in a wireless communication system including at least one antenna, comprising: a channel matrix correcting unit that estimates a channel matrix including channel response elements between antennas; a phase error estimating unit estimating a phase error resulting from a phase noise, a clock drift, and a frequency offset included in a received signal on the basis of a decoding result of encoded and transmitted information symbols in 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, wherein 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 correcting unit, and the waveform equalizing unit equalizes the waveform of the data symbols using the channel matrix including the original channel response elements.
