1. A method of communicating with an electronic device under test through a simulated radio channel of an emulator, the method comprising:

  • optimizing a cost function of a theoretical spatial cross correlation and a spatial correlation associated with a plurality of antenna elements coupled to an emulator in an anechoic chamber to determine weights of the plurality of antenna elements; and

    forming, based on the weights, a beam of a signal of at least one path of a simulated radio channel with at least two antenna elements of the plurality of antenna elements, wherein a direction of each path depends on a direction of each antenna element.
