Summary:
This paper describes the effectiveness of calibration technique for implicit beamforming which enables the transmission without the channel state information (CSI) feedback in massive MIMO system. First, we address the calibration technique using the circulation of self transmit signal. The effectiveness of calibration method is next verified by using 16-element testbed for the massive MIMO system. Finally, the throughput performance by the IEEE802.11ac based massive MIMO transmission with and without CSI feedback is verified when considering calibration errors which are obtained by the testbed.
