Influence of the posture in body surface to external UWB body area networks channels

This paper presents an analysis of the influence of the body posture in the communication channel from a device placed on the body surface to an external fix station for the 3.1-8 GHz frequency band. Standing and lying down positions are compared and rms delay spread and statistical parameters are extracted to model the channel according to the IEEE802.15.6 proposed CM4 model.
