Channel Estimation Algorithms and Their Impact on Wideband Millimeter Wave Channel Characteristics

Research output: Contribution to book/anthology/report/conference proceedingArticle in proceedingResearchpeer-review

Abstract

The demand for higher data rate has motivated research in
millimeter wave (mm-Wave) bands for 5G cellular systems.
Accurate channel characterization at mm-Wave bands has
gained significant interest in recent years, since it is important
for system design and performance evaluation of future
communication systems. In this paper, a mm-Wave channel
sounding campaign based on a rotational horn and a virtual
uniform circular array (UCA) was performed in a line-ofsight
(LOS) and obstructed-LOS scenario in an indoor environment.
Three channel estimation algorithms were implemented
for the UCA data and compared with the horn
antenna measurement results. The channel characteristics,
e.g. mean angle of arrival, angle spread, mean delay and
delay spread were analyzed for different algorithms. The
measured results demonstrated the impact of channel estimation
algorithms in radio channel parameters.
