Abstract
Wireless Body Area Networks (WBANs) have been developed as the human-body monitoring systems to predict, diagnose, and treat diseases. Since the signal transmission in WBANs takes place in or around the human body the channel fading significantly affects packet error rate and overall network performance. This paper focuses on the design and demonstration of an ultra-wideband (UWB) modem to be used in the WBAN applications, and the evaluation of its performance over Rayleigh fading channel. Results show how the fading channel affects the performance of the system.
