Abstract
A method for testing wireless performance of a MIMO wireless terminal includes: obtaining antenna pattern information of a plurality of antennas of the MIMO wireless terminal tested in an electromagnetic anechoic chamber; further obtaining a test signal according to the antenna pattern information of the MIMO wireless terminal; calibrating the test signal by using an error calibration joint matrix of the MIMO wireless terminal so as to obtain a transmitting signal for testing; and finally feeding the transmitting signal for testing into a plurality of measurement antennas of the electromagnetic anechoic chamber and transmitting the transmitting signal to the wireless terminal through the measurement antennas so as to test the wireless terminal.
