Wideband channel modelling in UHF band for urban area

Open publisher page 8 citations

Abstract

This paper studies the small-scale multipath propagation characteristics of a typical outdoor urban environment. Wideband channel sounding measurements are performed and findings are presented. Channel sounding is carried out at UHF band (250, 300, 350, 400 MHz) for static transmit and receive antennas. The power delay profile, mean delay spread, RMS delay spread, as well as coherence bandwidth have been estimated. The results show that the outdoor urban environment at UHF frequencies is a rich scattering environment, where spatial diversity can be applied.
