Title:
AUTONOMOUS RADIATION PATTERN GENERATION ANTENNA CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/116749
Kind Code:
A1
Abstract:
[Problem] To provide an autonomous radiation pattern generation antenna control device capable of setting a weight amount so that an appropriate radiation pattern can be generated according to a wireless environment. [Solution] An antenna control device comprises: a weight unit 101 in which a weight value to be superimposed on a transmission/reception signal is set in order to form a radiation pattern using a plurality of antennas; a weight synthesis unit 102 which superimposes the weight value of the weight unit 101 on the transmission/reception signal; a null scan unit 400 which outputs a reception level in the arrival direction of a reception signal; an arrival direction detection unit 310 which detects the arrival direction of the reception signal from the reception level; a distribution information calculation unit 320 which calculates distribution information of the detected arrival direction; and a radiation pattern selection unit 330 which selects a radiation pattern on the basis of the distribution information, and sets a weight value corresponding to the selected radiation pattern in the weight unit 101.
