Abstract

The paper presents the improvement offered by spatial diversity to reduce fading in ultra wideband (UWB) body-centric wireless communication channel in context of second order statistics for five different measured links, i.e., waist-to-chest, waist-to-head, waist-to-wrist, waist-to-ankle and waist-to-back. Average fade duration (AFD) and level crossing rate (LCR) values are presented and compared for diversity combined signal with respect to branch signals. In addition AFD and LCR of diversity combined signals are also compared for five different on-body channels and for three different locations in an indoor environment. Result and analysis of second order channel parameters shows the importance of considering these parameters when designing an enhanced body-area network system.
