Abstract
A testing system optimizes a cost function of a theoretical spatial cross correlation and a spatial correlation obtained with antenna elements for determining weights of the antenna elements, and forms a beam of a signal of at least one path of a simulated radio channel with at least two antenna elements of a plurality of antenna elements coupled to an emulator in an anechoic chamber. The at least two antenna elements are capable of polarizing the beam in a known manner.
