CALIBRATION DEVICE, WIRELESS COMMUNICATION DEVICE, SYSTEM, METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/173866
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a calibration device with which a wireless communication device having a plurality of transmit/receive units connected to respective elements of an array antenna can be calibrated simply, a wireless communication device, a system, a method, and a program. The calibration device (10) according to the present invention is a calibration device (10) for calibrating a wireless communication device (50) provided with: a first transmit unit (512) and a second transmit unit (522) which transmit transmission signals; and a first receive unit (518) and a second receive unit (528) which receive reception signals. The calibration device (10) is provided with: a measurement unit (11) which measures the level of a first calibration signal (S1) input into the first transmit unit (512) and output from the second receive unit (528), and the level of a second calibration signal (S2) input into the second transmit unit (522) and output from the second receive unit (528); and a control unit (12) which controls the gain of the second transmit unit (522) so that the difference between the level of the first calibration signal (S1) and the level of the second calibration signal (S2) becomes not more than a first predetermined value (L1).
