CONTROL DEVICE, DIFFERENTIAL DELAY ADJUSTMENT METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM FOR STORING DIFFERENTIAL DELAY ADJUSTMENT PROGRAM

WIPO Patent Application WO/2019/181257

A1

Provided are a control device, a differential delay adjustment method, and a differential delay adjustment program that enable improvement of reception accuracy in MIMO transmission. A control device (17) causes a first transmission system of a MIMO transmission device (10) to send a first-transmission-side clock transfer signal (first transfer signal), causes a second transmission system to transmit a second transfer signal, and causes the first transmission system to transmit a third transfer signal. The control device (17) acquires a first phase value and a second phase value. The first phase value is a phase value of the second transfer signal received by a second reception system that performs synchronous operation on the basis of a reception-side clock signal synchronized with a transmission-side clock signal by the first transfer signal. The second phase value is a phase value of the third transfer signal received by the second reception system that performs synchronous operation. On the basis of the first phase value and the second phase value, the control device (17) calculates a first correction value for correcting a first delay amount set value of a delay adjustment processing unit (14B1).
