Channel Verification Results for the SCME models in a Multi-Probe Based MIMO OTA Setup

MIMO OTA testing methodologies are being intensively investigated by CTIA and 3GPP, where various MIMO test methods have been proposed which vary widely in how they emulate the propagation channels. Inter- lab/inter-technique OTA performance comparison testing for MIMO devices is ongoing in CTIA, where the focus is on comparing results from various proposed methods. Channel model verification is necessary to ensure that the target channel models are correctly implemented inside the test area. This paper shows that the all the key parameters of the SCME models, i.e., power delay profile, temporal correlation, spatial correlation and cross polarization ratio, can be accurcately reproduced in a multi-probe anechoic chamber based MIMO OTA setup.MIMO OTA testing methodologies are being intensivelyinvestigated by CTIA and 3GPP, where various MIMOtest methods have been proposed which vary widely in how theyemulate the propagation channels.
