Beschreibung
Zusammenfassung:	A signal is transmitted and received between a base station device and a communication terminal device that are included in a communication system, through a multi-element antenna including a plurality of antenna elements. At least one of the base station device and the communication terminal device includes a PHY processing unit that is a calibration unit that performs calibration of phases and amplitudes of beams formed by the antenna elements when the signal is transmitted and received. The PHY processing unit obtains a correction value for the phases and the amplitudes of the beams in the respective antenna elements so that the phases and the amplitudes of the beams are identical among the antenna elements, and performs the calibration based on the obtained correction value.
