Abstract :
This paper presents experimental investigation of ultra wideband on-body radio channel in both the anechoic chamber and indoor environments including effects of time varying movements of various body parts on the the channel characteristics. Measured data are used to extract radio propagation channel parameters and investigate the influence of body movements on derived channel models. These models are applied in conjunction with different modulation techniques commonly used for impulse radios to evaluate the system performance of on-body UWB radio systems. Bit error rate and signal-to-noise ratio studies show that careful considerations need to be taken when choosing the modulation technique for optimal ultra wideband body-centric systems.
