Abstract
A control device causes a first transmission system in a MIMO transmission device to transmit a first transmitting-end clock transmission signal (first transmission signal), causes a second transmission system to transmit a second transmission signal, and causes the first transmission system to transmit a third transmission signal. The control device acquires a first phase value and a second phase value. The first phase value is a phase value of the second transmission signal received in the second reception system operating based on a receiving-end clock signal synchronous with a transmitting-end clock signal by the first transmission signal. The second phase value is a phase value of the third transmission signal received in the second reception system in synchronous operation. The control device calculates a first correction value for correcting a first delay amount set value of a delay adjustment processing unit based on the first and second phase values.
