Abstract
This paper describes a measurement system enabling
the complete real-time characterization of the wideband radio channel.
The system is based on a wideband radio channel sounder and a spherical
antenna array, and it aims to describe the three-dimensional (3-D)
spatial radio channel seen by the mobile terminal, including
polarization. This information is highly valuable in designing antennas
for mobile terminals. The spatial properties of the measurement system
are analyzed through test measurements in an anechoic chamber. The
system has a 40/spl deg/ spatial resolution and a 17 dB cross
polarization discrimination. The values are well above those of a small
mobile terminal antenna. The dynamic range in the spatial domain is 12
dB. The measurement is very fast, which makes real-time channel
acquisition practical at normal mobile speeds.
