Abstract
A base station apparatus switches between a communication mode for performing communication with a communication party and a calibration mode for performing a calibration process. In the calibration mode, a weight vector in accordance with a first algorithm for performing a null steering directivity control for orienting an area of drastically-lowered antenna gain in the direction of arrival of a reception signal. Furthermore, multiple transmission signals weighted by the acquired weight vector are output, and a correction value for readjusting the result of the null steering directivity control is acquired from a control PC. In the communication mode, multiple transmission signals are corrected by using the correction value acquired in a calibration mode, and the corrected signals are output.
