Abstract

Abstract: A time domain (TD) solution based on uniform theory of diffraction-physical optics (UTD-PO) was presented to analyze the multiple diffraction propagation characteristics of UWB signals under NLOS environment. The solution provided a simplified method, which utilized a recursion relation and did not need to incorporate the slope diffraction in the transition zone. The channel impulse response of the renowned Bertoni models was derived and the received signals could be predicted through a simple operation of convolution. The numerical results show that the proposed solution based on UTD-PO can find application in the analysis of multiple diffi-action and significantly reduces the computational time. In addition, the attenuation of the received signal caused by the wedge-shaped obstacle is greater than that caused by the cylindrical obstacle
