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