摘要
A method for wirelessly calibrating/testing RF and digital components of a multi-antenna device under test includes the step of wirelessly transmitting a first signaling information between the device under test and a device tester, the first signaling information indicating a calibration request, wherein the first signaling information is transmitted by the device under test or the device tester. Further, the method includes the step of estimating, in response to the first signaling information, channel transfer function matrices between active antenna ports/RF ports of the device under test and antenna ports of the device tester using reference signals wirelessly transmitted between the device tester and the device under test or vice versa.
