A Novel Probe Selection Method for MIMO OTA Performance Testing

Abstract

This letter presents a novel probe selection method for multiple-input–multiple-output (MIMO) over-the-air (OTA) testing. It can effectively reduce the number of probes used in anechoic chamber, which further reduces the ports of the channel emulator. Two basic channel models are used to validate the performance of this method. The simulation results demonstrate that it can reconstruct the channel environment around the device-under-test in a multiprobe anechoic chamber with high accuracy. In addition, the impact of different probe configuration setups on the accuracy of test results are discussed.
