Patent ID: 8254476

Claim:
A wireless communication device that transmits a wireless signal by performing linear precoding processing using a plurality of transmission antennas, comprising: a phase pattern control unit configured to select a phase pattern that reduces a peak-to-average power ratio; a phase rotation unit configured to perform phase rotation on a modulation signal using the phase pattern selected by the phase pattern control unit; a control signal generation unit configured to generate a control signal based on the phase pattern selected by the phase pattern control unit; and a precoding unit configured to perform linear precoding processing on output signals from the phase rotation unit and output signals from the control signal generation unit, wherein the phase pattern control unit includes: a plurality of peak value calculation units, each configured to perform phase rotation on the modulation signal corresponding to a respective pre-determined phase pattern; and a phase pattern selection unit configured to select a phase pattern based on outputs of the plurality of peak value calculation units.
