Abstract
A method operative on a wireless transceiver device for performing beamforming calibration includes: measuring at least one joint signal response of at least one circuit loopback between a transmitter of the wireless transceiver device and a receiver of the wireless transceiver device to determine the measurement result; and calibrating joint signal path mismatch according to the measurement result for s multiple antenna beamforming system operating on the wireless transceiver device.
