FIELD: information technologies.
SUBSTANCE: calibration is realised for transmission channel of device that transmits information to multiple devices along lines of wireless communication, and channels of reception of multiple devices that receive information along one of wireless communication lines, using multiple estimates of direct communication line channel, received from at least some of multiple devices, and multiple estimates of reverse communication line channel from multiple devices.
EFFECT: provision of antenna array calibration used in wireless communication devices.
