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.

一种用于 MIMO OTA 性能测试的新型探针选择方法

这封信提出了一种用于多输入多输出 (MIMO) 空中 (OTA) 测试的新型探头选择方法。它可以有效减少消声室中使用的探头数量，从而进一步减少通道仿真器的端口。使用两个基本通道模型来验证该方法的性能。仿真结果表明，它可以高精度地重建多探头电波暗室中被测设备周围的通道环境。此外，还讨论了不同探头配置设置对测试结果准确性的影响。
