A Fast Rotating-Mirror Sounder for Dynamic Millimeter-Wave Channel Characterization

Al-Ameri, Ali LU ; Sanchez, Juan LU ; Tufvesson, Fredrik LU orcid and Cai, Xuesong LU (2024)
Abstract
A deep understanding of double-directional wireless
channels is imperative for wireless system design. This necessitates
the development of precise channel models through channel
sounding. Given the dynamic nature of wireless channels, a short
measurement time is highly desirable. In this paper, we present
and validate a dual-polarized millimeter-wave channel sounder
that uses a rotating mirror mechanism. This enables quick sweep
of the azimuthal plane to capture spatial channel characteristics
at 27.5-28.5 GHz in less than a second. This is radically faster
than conventional virtual-array channel sounders. Following a detailed
discussion of the sounder implementation and the rotating
mirror... (More)

than conventional virtual-array channel sounders. Following a detailed
discussion of the sounder implementation and the rotating
mirror concept, we present an indoor verification measurement
scenario. The results demonstrate several discernible propagation
paths with parameters that agree with the actual geometry of the
indoor measurement environment. (Less)
