Abstract :
In this paper, the characteristics of ultrawideband (UWB) channels on outdoor roadway and indoor parking environments are investigated. A set of propagation measurements were conducted on roadways and in underground parking garages, and the resulting propagation data consist of approximately 1200 measured signals. Multipath properties are characterized using tapped-delay-line and Saleh-Valenzuela (S-V) models. Power-law-type decay patterns are observed in the ray-energy decay, as well as in the power delay profile. Results are compared with existing UWB models, including the IEEE 802.15.4a channel model.
