Modeling of
Scenario
|
|
The
simulation scenario was modeled with a 3D vector database of the
buildings and the underling digital terrain elevation
database. The location of the base station, as well as
the two trajectories of the receiver, which are taken
into account for the comparison, are shown in the figure as well
(click to enlarge).

Information
about Measurements
|
|
The MIMO
measurement campaign was performed by the
Institute of
Information Technology of the
University of
Technology Ilmenau, in July 2008. The measurements
were done in the framework of a COST project, where the
city center of Ilmenau is used as a
reference scenario for the development and
validation of MIMO channel models. The measurement campaign focused
on gathering realistic channel data in an urban
macro cell environment in the 3GPP Long Term Evolution
(LTE) frequency band. Channel sounding was performed for
three base stations and one relay station on 22 receiver
trajectories distributed all over the city center of
Ilmenau.

Comparison of Measurement Data with Prediction
Results
|
|
For
comparison of measurement and prediction data, a
2x2 subset of the measured channel data was used. The
wave propagation simulations have been performed with
the Intelligent Ray
Tracing Model (IRT), using the 3D model of Ilmenau
city center shown in the figure above. The following
graphs show the comparison between measurement (blue
curves) and prediction (red curves) of different channel
parameters along the two receiver trajectories.
