摘要： A testing system comprises a noise source coupled to at least two antenna elements. The noise source forms a total noise power on the basis of a total signal power received by the emulator, a gain of at least one antenna-specific channel between the emulator and the antenna elements, and a desired signal-to-noise ratio. The noise source transmits noise at the total noise power from the at least two antenna elements to the device under test wirelessly.

摘要： An emulating system of an over-the-air test comprises a radio channel emulator, a selector, a connector and a plurality of antenna elements placed around a test spot for an electronic device under test. The selector receives data on a simulated radio channel from the radio channel emulator and selects a subset of a plurality of positions of antenna elements on the basis of the data. The connector connects only the antenna elements in the subset and the radio channel emulator for physically realizing the simulated radio channel.

摘要： 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.

摘要： A radio channel is formed for estimation, the radio channel including dominant paths from a digital impulse response estimate of a channel relating to a radio system. A divider divides the impulse response estimate temporally into at least two subsignals. An analyzer determines whether a distribution of the amplitude values of at least one subsignal is gaussian or non-gaussian. A searcher searches for a highest amplitude value in each subsignal, which is determined to be non-gaussian. A generator may form a radio channel for a radio channel simulation, the radio channel including each propagation path corresponding to the highest amplitude value in each subsignal determined to be non-gaussian.

摘要： A preselector forms a plurality of preselections, by generating, for each preselection, a predetermined number of random locations, each location being for an antenna element of the predetermined number of antenna elements around a device under test in an over-the-air test. A selector selects, for at least one path of a radio channel to be simulated, a preselection from among the plurality of preselections for which an absolute error between a theoretical and real spatial correlation is below a predetermined threshold. A connector connects the antenna elements at the locations of the selected preselection and the radio channel emulator together for physically realizing the simulated radio channel for the device under test and the radio channel emulator.
