Abstract
Ultra wideband (UWB) propagation is antenna-dependent, and multipath components experiencing specular diffraction or arriving at different angles have different shapes. To utilise the diversity of the multipath components, this study proposes a statistical model which incorporates directional parameters, such as elevation and azimuth angles by extending the IEEE802.15.3a model. Based on this model, a UWB directional simulator is developed. A novel multi-template subtractive deconvolution is applied to an extensive measurement campaign and simulated profiles. The use of multi-templates makes possible the directional estimation of the multipath components with a single receive antenna, and the use of subtractive deconvolution allows for the resolution of overlapping components and higher energy capture. Directional characterisation of UWB channels facilitates performance evaluation studies and achieves more accurate positioning, imaging and Rake receiver design.
