Second order statistics of ultra wideband on-body radio channels

The paper investigates the effect of the body movements on the second order statistics of ultra wideband (UWB) on-body radio channel. A measurement campaign was performed considering four different body-links, namely: waist-to-head, waist-to-chest, waist-to-wrist, and waist-to-ankle, with the subject performing designed movements of different nature, in order to cover a wide range of scenarios. Analysis and comparison of second order channel parameters such as level crossing rate, average fade duration and fade probability for the proposed on-body propagation links is being performed for different environments to highlights their importance for designing an enhanced body-area networks.
