  • Over-the air test
    Patent number: 9787414
    Abstract: A radio channel generator has a radio channel model predistorted on the basis of a predetermined chamber model. An emulator receives the weights of the radio channel model predistorted on the basis of the chamber model. A transmitter feeds a communication signal to the emulator. The emulator weights the communication signal with the radio channel model predistorted on the basis of the chamber model. The over-the-air antennas receive the weighted communication signal and transmit it to a device under test. The chamber model is based on a simulation or a measurement. The chamber model takes into account undesired interactions in the over-the-air chamber for cancelling them during the radio channel emulation.
    Type: Grant

  • Over-the-air test
    Patent number: 9705190
    Abstract: An apparatus forms a weight for each signal path associated with an antenna of a plurality of antennas around a test zone in an over-the-air chamber by a comparison of a desired target electric field based on a radio channel model and an electric field obtainable by the plane waves associated with the test zone, the plane waves being transmittable by the antennas and being based on at least one basis waveform in each signal path.
