a distribution synthesis unit; and
a control unit, wherein
the control unit causes a transmission calibration signal to be sent to each transmitter to be orthogonalized in frequency for each transmitter,
each transmitter sends the transmission calibration signal being orthogonalized in frequency,
the distribution synthesis unit synthesizes the transmission calibration signals being sent from the transmitters and transmits the synthesized signal to the calibration transmitter-receiver, and
the control unit applies phase modulation to a phase of a subcarrier being used by each transmitter for sending out the transmission calibration signal, for each transmitter.
