This paper reports on a real-world wireless channel measurement campaign for
in-vehicle scenarios in the ultra wide bandwidth (UWB) frequency range of
3-11 GHz. The effects of antenna placement in the vehicle's passenger
compartment, as well as the effects due to the presence of passengers are studied.
The measurements have been carried out in the frequency domain and the
corresponding channel impulse responses (CIRs) have been estimated by inverse
Fourier transform. The inuence of a specifc band group selection within the
whole UWB range is also given. Statistical analysis of the measured channel
transfer functions gives a description of the wireless channel statistics in the form
of a generalized extreme value process. The corresponding parameter sets are
estimated and documented for all permutations of antenna placement and
occupancy patterns inside the vehicle's passenger compartment. Further, we have
carried out a feasibility study of an in-vehicle UWB based localization system
based on the time of arrival (TOA)). The positioning performance is evaluated in
terms of average error and standard deviation.
