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.

Over-the-air test

A receiver receives at least one radio frequency band. A signal processor separates a signal space associated with the at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one radio frequency band. For a simulation, a memory stores the environment data of the at least one radio system based on the background space under control of the signal processor.

Data collection and simulation

A frequency manipulator comprises a frequency transformer and a frequency retransformer. The frequency transformer receives each of at least one signal in a known band from at least one transmitter, transforms the known band of each signal into a predetermined band and forwards each signal in the predetermined band to a channel device. The frequency retransformer receives each signal from the channel device, retransforms the predetermined band of each signal to the known band and forwards each signal in the known band to at least one receiver.
