Abstract
In an adaptive array terminal, at least one of two antennas is a movable type antenna. The correlation value of respective reception signals of the two antennas is displayed on a display unit of the terminal. Accordingly, the user can adjust the antenna angle such that the correlation value of the reception signals of the two antennas becomes smaller. Alternatively, the control unit of the terminal can automatically adjust the antenna angle such that the antenna correlation value of the two antennas becomes lower than a predetermined value.
