Modeling of UWB channels by using an efficient ray tracing procedure

In this paper, we propose a novel and efficient procedure to extract the UWB propagation channel parameters, that employs a RT simulation carried out at different frequencies and followed by a proper processing of the simulated data. A parallel ray approximation, usually adopted in array analysis, is successfully used to dramatically reduce the computational time of the procedure. An excellent agreement between simulation results and measured data is achieved, showing that the RT-based tool can be successfully used for accurate and reliable site- planning in UWB systems.
