Numerical radio propagation characterisation and system level modelling for ultra wideband on-body communications

In this paper a radio propagation studies in addition to system performance evaluation for ultra wideband (UWB) (3-10.6 GHz) frequencies is being presented based on parallel finite-difference time-domain technique. In an indoor environment, effect of human body postures on the propagation channel and system performance for body area network is being studied. Results show the dependence of propagation channel characteristic and system performance on the human subject postures. Therefore, careful consideration of postures in addition to subject are important for reliable radio channels and system performance.
