Abstract
This letter presents a novel scheme to construct multiple wireless channels for multiuser over-the-air (OTA) testing in a limited zone without physical separation. The system model of the two devices under test (DUTs) OTA testing is provided, according to which the pre-compensation matrix is proposed to mitigate the crosstalk between the two DUTs. Experimental validation in an anechoic chamber environment demonstrates the successful reconstruction of two distinct wireless channels for adjacent DUTs, achieving inter-user isolation exceeding 15 dB. The proposed scheme might be a promising option for multiuser OTA testing.
