Over-the-Air Testing for Dual-Polarized MIMO Devices:Setup Design and Validation
文献摘要：
Over-the-air(OTA)testing is considered as the only feasible solution to evaluate radio per-formances of the fifth-generation(5G)wireless de-vices which feature two important technologies,i.e.,massive multiple-input multiple-output(MIMO)and millimeter-wave(mmWave).The multi-probe ane-choic chamber(MPAC)based OTA setup is able to emulate realistic multipath propagation conditions in a controlled manner.This paper investigates an MPAC OTA setup which is capable of evaluating the perfor-mances of 5G base stations as the devices-under-test(DUTs)which are equipped with dual-polarized an-tennas.Both end-to-end setup and probe configura-tion for the considered MPAC setup will be elaborated.Furthermore,since building a practical MPAC setup is expensive,time-consuming,and error-prone,an end-to-end software testbed is established for validation purpose to avoid technical risks before finalizing an MPAC setup.The architecture of the testbed is pre-sented,which can emulate both the channel profiles perceived by the DUT and the physical-layer behav-iors of the considered link conforming to 5G new ra-dio(NR)specifications.Results show that the perfor-mances under the emulated channel agree well with those under the target channel,validating the accuracy and effectiveness of the MPAC method.
