3D hybrid EM ray-tracing deterministic UWB channel model, simulations and measurements

Abstract

Aim of this contribution is to validate our deterministic UWB channel model which integrates the real characteristics of the UWB antennas in the whole effective channel. Our analysis relies on a UWB ray tracing approach since this reflects the dependence on the angle of arrival (AoA) and angle of departure (AoD) of any multipath. In the meanwhile, EM-Simulation tool has been used to compute the transfer functions of the real antennas used. Office environment was considered in both the simulation and measurements with Line of Sight (LoS) and NLoS scenarios. A comprehensive comparison between the deterministic channel model and the real measurements from IMST shows a good agreement between them regarding to the Channel Impulse Response (CIR), Power Delay Profile (PDP) and Delay Spread (DS). This can offer the UWB system designers an efficient and reliable tool to examine their systems performance on a real world simulations.
