Ultra-wide band wireless body area network channel measurements and modeling

With the development of communication technology,high-speed short-range ultra-wide band wireless body area networks have received increasing attention.This paper used frequency domain-based wireless channel measurement platform to measure three types of human body channel in both the office and anechoic environments within the 3-5 GHz frequency.The statistical analyses gave a wireless channel model with the path loss and power delay profile.Simulations show that this model is more accurate than the standard models for the mean excess delay spread,the root-mean-square(RMS) delay spread,and the number of multi-paths in the 20 dB ranges.
