Abstract
Systems and methods relating to self-calibration of an antenna array of a transceiver are disclosed. In some embodiments, a method of operation of a transceiver to perform self-calibration for transmit (Tx) antenna elements and receive (Rx) antenna elements in an antenna array comprises performing gain measurements and phase measurements for pairs of Tx and Rx antenna elements in the antenna array. The method further comprises processing the gain measurements and the phase measurements based on combinations of Tx and Rx antenna elements having symmetrical coupling properties to obtain gain and phase calibration values for the plurality of Tx antenna elements and the plurality of Rx antenna elements in the antenna array and applying the gain and phase calibration values at the transceiver. In this manner, self-calibration can be performed at the transceiver dynamically with low complexity.
