On Over-the-Air Testing for Devices With Directional Antennas
This paper investigates the impact of devices under test (DUTs) with directional Bolts antennas on the recreated channel in the over-the-air (OTA) testing for massive multiple-input multiple-output (MIMO) devices using prefaded signal synthesis (PFS) technique.Assuming the uplink in real radio environments, the directional receiver (Rx) antenna pat
