Verification of emulated channels in multi-probe based MIMO OTA testing setup

MIMO OTA testing methodologies are being intensively investigated by CTIA and 3GPP. Different channel emulation techniques to create a desired propagation environment in an anechoic chamber have been proposed in the literature. In this paper, the focus is on the measurement verification of two channel emulation techniques, namely plane wave synthesis and prefading signal synthesis in a practical multi-probe anechoic chamber setup.
