摘要：
A study of UWB on-body communication system performance, with the WiMax off-body electromagnetic interference (EMI) existence, is presented. Firstly, a compact UWB antenna with good on-body performance is verified and chosen as our reference antenna. Using this realistic antenna, channel transfer function (CTF) of UWB on-body channel in an indoor room is investigated by measurements. Based on the measured data, the parameters of its pathloss model and its power delay profile (PDP) model are extracted respectively. Secondly, a new body channel communication system model, composed of the on-body and off-body dual-link channel, together with UWB and WiMax signal models are presented. Finally, UWB on-body communication performances under different WiMax off-body EMI levels are studied by simulation. Simulated results show that this on-body system performance is quite limited and easily affected by the off-body WiMax EMI. It is pointed out that the existing UWB on-body communication abilities should be greatly improved when WiMax off-body EMI signals are considered.
