In this contribution we present a modular IEEE
802.15.4a UWB demonstrator platform. The demonstrator supports
a one-way communication link and allows for ranging and
communication experiments.
The proposed system can be used for hardware verification
by substituting the different modules, but also to verify different
receiver structures and channel models. The data processing is
held offline, to allow for highest flexibility in the analysis.
A coherent receiver architecture is chosen to verify the
demonstrator system in line-of-sight (LOS) and non-line-of-sight
(NLOS) scenarios in outdoor, industrial, office and residential
environments. Channel estimation and the parametrization of
the pathloss model are carried out in these environments. Finally,
the root mean square delay spread is calculated, and the major
differences between the scenarios are pointed out.
