In the proposed algorithm, the mutual coupling effect between antennas is introduced into the channel matrix and the over-the air (OTA) calibration algorithm is combined with the AR model based prediction channel matrix. The algorithm achieves simultaneous calibration for the loss of reciprocity caused by radio frequency nor-ideality and channel time varying characteristics.
