Abstract
Employing large-scale antenna configuration is seen
as a key enabling radio technology for 5G and beyond
communication systems. This work presents validation of a
home-developed ray tracing (RT) tool for massive multipleinput
multiple-output (MIMO) system in the millimeter-wave
(mmWave) frequency bands. For this purpose, a channel sounding
campaign in an indoor entrance scenario using a massive
MIMO systems based on virtual array concept is presented. The
channel measurement of 6 GHz bandwidth (26.5-32.5 GHz) is
first demonstrated, with a virtual uniform circular array (UCA)
consisting of 720 antenna elements located at the transmitter
position on the turntable and one antenna at the receiver
position. The impact of order of interactions e.g. reflections and
diffractions on the channel impulse responses (CIRs) is analyzed
in the RT simulation. The comparison between RT simulated and
measured results shows a reasonable level of agreement.
