| 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. | ||

| 主权项 | 1. A method of communicating wirelessly with an electronic device under test surrounded by antenna elements, the communication being performed through a simulated radio channel of an emulator, the method comprising: transmitting noise wirelessly at a total noise power from at least two antenna elements to a device under test, the total noise power being based on a total signal power received by the emulator, a gain of at least one antenna-specific channel between the emulator and antenna elements, and a desired signal-to-noise ratio; forming a complex Gaussian noise corresponding to a desired noise power distribution of the total noise power; and feeding the Gaussian noise to the at least two antenna elements. | ||
