Abstract (in Japanese) (See Japanese page) 
(in English) Calibration is necessary for implicit feedback to perform downlink transmit beamforming exploiting uplink channel state information (CSI) on multiuser multiple-input multiple-output (MIMO) systems. In this paper,
we present calibration schemes that combine calibration coefficients calculated for multiple stations (STAs) to improve accuracy. On massive antenna systems, i.e., with a large number of antennas, computer simulations show that combining calibration schemes achieve more accurate calibration than no-combining scheme.
