Abstract

The uniform geometrical theory of diffraction and ray tracing technique is used to simulate ultra wideband signal multipath propagation characteristics. The simulation model covers indoor office and outdoor corridor with thick wall and metal doors. The range of path loss exponent of distance is obtained by regression analysis, and the lognormal distribution about shadowing fading is got by the fitting and test. The distance-dependence path loss in the indoor and indoor to the corridor present lognormal distribution characteristics. Through the comparative research, the signal of the transmission metal door has a decisive influence on the corridor environment.
