Abstract
The disclosure provides a transceiver of a communication system using hybrid beamforming and performing an antenna calibration method. In an exemplary embodiment in accordance with the disclosure, the transceiver may generate a plurality of scrambling sequences. The transceiver may comprise a plurality of coupling circuits to receive a feedback signal. The transceiver may use the plurality of scrambling sequences to recover the transmit signals output by the antenna elements from the feedback signal. Thus, the transmitter may perform antenna calibration for each antenna element.
