CALIBRATION OF ANTENNA MATRIX FOR MULTI-INPUT-MULTI-OUTPUT SYSTEMS OF WIRELESS COMMUNICATION Russian patent published in 2010 - IPC H04B7/06 

Abstract RU 2395163 C2

FIELD: information technologies.

SUBSTANCE: substance of invention consists in calibration of antenna matrix of access point in wireless network, including stages of receiving the first channel estimates that correspond to transfers from access point to each of at least two antennas, at least two access terminals, detection of the second channel estimates that correspond to transfers from each of at least two antennas of at least two of specified access terminals to point of access, identification of calibration ratio on the basis of mentioned estimates and calibration of antenna matrix of access point by application of calibration ratio to transfer scale of access point.

EFFECT: expansion and improvement of wireless communication devices.
