Beamforming calibration system and method

A beamforming calibration method for a transmitter, a receiver, and a computing device, the transmitter comprising a plurality of transmitting antennas, the beamforming calibration method comprising:

• providing, by the computing device, a plurality of phase sets to the transmitter;
• performing the following steps when the computing device provides a first phase set among the plurality of phase sets to the transmitter:
• (a) using, by the transmitter, the first phase set to set phases of the plurality of transmitting antennas;
• (b) receiving, by the receiver, wireless transmission signal from the transmitting antennas to obtain a first radiation pattern corresponding to the first phase set;
• and
• (c) comparing, by the computing device, the first radiation pattern with a predetermined pattern to calculate a pattern similarity score corresponding to the first phase set;
• selecting, by the computing device, a calibration phase set among the plurality of phase sets according to the pattern similarity score of each phase set;
• and
• providing, by the computing device, the calibration phase set to the transmitter to calibrate beamforming.
