In this paper, the effect of multiple access (MA) schemes of impulse radio on the power parameters of multiuser interference (MUI) is examined. More specifically, we investigate the ways in which the different MA schemes affect the average power, peak power, and the peak-to-average ratio (PAR) of the matched filtered version of the MUI signal. The results of the analysis performed for a simplified...
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...
