Abstract
Standardization work for over-the-air (OTA) testing of multiple-input-multiple-output (MIMO) capable terminals is currently ongoing in COST IC1004, 3GPP, and CTIA, where a multiprobe anechoic chamber based method is a promising candidate. Setting up a multiprobe configuration with channel emulators is costly, so finding ways to limit the number of probes while still reproducing the target channels accurately could make the test system both cheaper and simpler to implement. Several probe selection algorithms are presented in this paper to address this issue. The proposed techniques provide a probe selection framework for the channel emulation techniques published in the literature. Simulation results show that good channel emulation accuracy can be achieved with the selected subset of probes for the considered target channel models. The probe selection algorithm is further supported by measurement results in a practical multiprobe setup.

Summary
Over-the-air (OTA) testing of the radio performance of mobile terminals has the advantage of not needing to break or otherwise modify the mobile device. Several papers have addressed OTA testing for MIMO devices in multi-probe anechoic chamber setups with emphasis on channel modeling, where the goal is to accurately reproduce realistic channel models in the test volume. The cost of the multi-probe anechoic chamber setup mainly depends on the channel emulators and the number of probes required for reproducing the desired channel models. The probe selection algorithm for a multi-cluster channel model is supported by measurements in a practical 2D multi-probe setup
