| Abstract(in English) | It is necessary to calibrate uplink channel state information estimated for transmit beamforming on multiuser multiple-input multiple-output (MIMO) systems with implicit feedback (IFB). We propose combining calibration, a scheme in which multiple calibration coefficients are calculated and then combined to improve the calibration accuracy. In this paper, we develop real-time multiuser MIMO transmission equipment with an IFB mode using field programmable gate array (FPGA), and we evaluate performance of combining calibration by it in an actual radio environment. We show that combining calibration has better performance compared to a conventional, no-combining calibration scheme. |
