Systems and methods for radio channel emulation of a multiple input multiple output (MIMO) wireless link
Abstract:
Systems and methods for testing a wireless device under test (DUT) using over the air (OTA) channel emulation are disclosed herein. According to an aspect, a system is disclosed for testing a wireless DUT having a DUT antenna array. The system includes a probe antenna array, a shielded test chamber, a radio channel emulator, and a wireless communication emulator. The probe antenna array is electrically coupled with the radio channel emulator, and the shielded test chamber is configured to position the DUT antenna array in a radiative near field region of the plurality of probe antennas. The wireless communication emulator is operatively coupled with the radio channel emulator and is configured to emulate an electrical coupling between at least one antenna port of the DUT and at least one radio channel model of the radio channel emulator.
