Zusammenfassung:A radiowave propagation measurement system for wideband multichannel multiple-input-multiple-output (MIMO) measurements at 5.3 GHz is presented. The MIMO channel matrix of size 32/spl middot/32 can be measured using microwave switches at the transmitter (TX) and the receiver (RX). The system is capable of measuring direction of departure and direction of arrival with a dual polarization in both TX and RX. The antenna configuration can be selected to include a planar array or semispherical groups at each end of the link. A high-power switch is used at TX to enable large measurement distances. Results from a calibration in an anechoic chamber and from the measurement campaigns are shown.
