Deterministic UWB Wave Propagation Modeling for Localization Applications based on 3D Ray Tracing

For the assessment of radio based localization applications deterministic channel models are required that allow for the simulation of wave propagation in realistic environments. This paper describes the extension of the deterministic narrow-band wave propagation modeling approach of ray tracing to ultra wideband (UWB) channels. A channel model is presented that permits the simulation of wave propagation in realistic three-dimensional environments over the entire frequency range of UWB applications from 3.1 to 10.6 GHz. Simulation results for the impulse response and the power delay profile in a typical indoor scenario are shown. From a set of simulation results statistics are extracted and compared to already standardized statistical UWB channel models
