1. A wireless apparatus comprising:

  • a mode selection unit operative to select a communication mode for performing communication with a wireless apparatus to be communicated or a calibration mode for a calibration process;

    a weight vector acquisition unit operative to acquire a weight vector by executing a first algorithm, which is for a null steering directivity control, on a plurality of reception signals when the calibration mode is being selected by the mode selection unit and to acquire a weight vector by executing a second algorithm different from the first algorithm when the communication mode is being selected by the mode selection unit;

    an output unit operative to output a plurality of transmission signals weighted by the weight vector acquired by the weight vector acquisition unit; and

    a correction value acquisition unit operative to acquire a correction value for readjusting the result of the null steering directivity control after the transmission signals are output by the output unit when the calibration mode is being selected by the mode selection unit, whereinthe output unit outputs a plurality of transmission signals after correcting the transmission signals by using the correction value acquired by the correction value acquisition unit when the communication mode is being selected by the mode selection unit.
