1. A control device of a wireless communication system including the control device that is installed on a moving object and moves, a first communication device that transmits a desired signal to the control device by a first wireless method, a second communication device that transmits an interference signal interfering with the desired signal by a second wireless method, and one or more third communication devices, the control device comprising:
a receptor that acquires a wireless signal including a reference signal transmitted from the third communication device in the vicinity of the second communication device by a third wireless method and a desired signal transmitted from the first communication device by the first wireless method;
an extractor that extracts the reference signal from the wireless signal based on the third wireless method;
an estimator that estimates a first propagation channel between the third communication device and the control device based on the reference signal; and
a beam controller that directs a null of a reception beam in an arrival direction of the reference signal based on the first propagation channel.
