摘要： A radio channel generator has a radio channel model predistorted on the basis of a predetermined chamber model (98). An emulator (118) receives the weights of the radio channel model predistorted on the basis of the chamber model (98). A transmitter (122) feeds a communication signal to the emulator (118). The emulator (118) weights the communication signal with the radio channel model predistorted on the basis of the chamber model (98). The over-the-air antennas (102-116) receive the weighted communication signal and transmit it to a device under test (300). The chamber model (98) is based on a simulation or a measurement. The chamber model (98) takes into account undesired interactions in the over-the-air chamber for cancelling them during the radio channel emulation.

摘要： Apparatus comprises a receiver (112) receiving wireless transmission of a real radio system from at least one base station (100, 196, 198) of a radio system as a function of reception direction. The transmission comprises predetermined data. The apparatus comprises also a processing unit that forms taps of a delay profile on the basis of comparison between the data that is received and corresponding predetermined data. The processing unit estimates direction for the taps of the delay profile on the basis of a reception direction of the transmission, and forms radio channel data by associating the taps of the delay profile with the estimated direction. The radio channel data is for a radio channel model of a MIMO emulation in an OTA chamber having a plurality of antennas around a test zone where a device-under-test may be placed.
