Over-the-air test

摘要

A simulated radio channel is shifted with respect to a plurality of antenna elements coupled with an emulator for communicating with a device under test by using different directions for the simulated radio channel in an anechoic chamber.

1. A method of communicating with an electronic device under test through a simulated radio channel of an emulator, the method comprising:
minimizing a cost function of a theoretical spatial cross correlation and a spatial correlation obtained with antenna elements to determine weights associated with the antenna elements, the cost function being minimized with respect to at least one of gain factors associated with the antenna elements and the weights associated with the antenna elements, thereby enabling the simulated radio channel to be electronically rotated around the device under test without moving the antenna elements; forming, on the basis of the weights, at least one beam of a simulated radio channel with at least two antenna elements; and shifting the simulated radio channel with respect to a plurality of the antenna elements coupled with the emulator to communicate with the device under test by using different directions for the simulated radio channel in an anechoic chamber.
