Abstract :
Ultra wideband (UWB) communication is a promising technique for biomedical body area networks (BAN). In this paper, the performance of wearable and implant BAN links on chest, which correspond to communication links of chest-to-waist and chest inside-to-outside respectively, are investigated. The channel models are first derived based on the frequency-dependent finite difference time domain (FDTD) method and a realistic-shaped human body model with an emphasis on the statistical variations of body postures. Then the bit error rates (BER) for a RAKE receiver are obtained for these two links.
