| Abstract(in English) | Transmission schemes using CSI at transmitter have been widely investigated to achieve efficient transmission. Transmitting channel information required for performing the schemes can be given by CSI feedback, but it consumes much control information as the number of antennas or subcarriers becomes larger. On the other hand, transmitter can have CSI by means of channel reciprocity in TDD systems. This paper presents an auto-calibration method that realizes this reciprocity. In this method, calibration coefficient is obtained by bidirectional channel measurement among the multiple antennas in the transmitter. The results of experiment and simulation demonstrate the performance of the method. |
