Research Of Wireless Body Area Network Coommunication Under Electromagnetic Interference

During past several years, wireless body area communication especiallyits application in medical treatment have been paid so many attention bycorporations, universities and institutions, and some basic researchaccomplishments has been achieved. Up to now, some body area channels hasbeen defined and planed, including the in-body to in-body channel, in-body toon-body channel, on-body to on-body channel, and in-body to out-bodychannel. It is critical to build the body area channels which are suitable forwireless body area network and evaluate the transmission performance and itsanti-electromagnetic interference ability of the communication systems inwireless body area network.In this thesis, firstly, on-body to on-body communication, as the mostcommon scenario in wireless body area network, is considered, and measuredby real human body experiments and processed by algorithms. Then, with theobjected on-body to on-body channel extracted, including the body pathlosschannel model and the body power delay profile channel model, the UWBcommunication system which is suitable for body communication isconstructed. Finally, based on this UWB system and the WiMax interferingsystem, the on-body transmission performance and its anti-interference abilityof UWB system are investigated.The technique methods and research ideas in this thesis could providefoundation and guide for body area communication antenna design, body areachannel modeling, and evaluation of the transmission performance and anti-interference ability of the communication systems, and the co-existencebetween multi-mode in wireless body area network.
