Performance of On-Body Chest-to-Waist UWB Communication Link

On-body area ultra wideband (UWB) communication is promising for biomedical applications. In this letter, the performance of an on-body UWB chest-to-waist link, which corresponds to a communication link from a biotical sensor at the chest to a coordinator receiver at the waist, is investigated. The channel model is first derived based on the frequency-dependent finite difference time domain method and a realistic-shaped human body model with an emphasis on the statistical variations of body postures. Then the bit error rate for a RAKE receiver is obtained.
