A good understanding of the fading characteristics in high speed railway environment is essential for the design of a high reliable railway wireless network. In this paper, measurements have been taken in both high speed viaduct and terrain cutting scenarios using track side base stations (BSs) of the railway wireless network in China. The measurement sites have been chosen with special care; thus the whole measured route can be characterized either by viaduct or terrain cutting. Kolmogorov-Smirnov (K-S) test has been first introduced in the statistical analysis to find out which is the most appropriate model for the small scale fading envelope. Though both Rice and Nakagami distributions provide a good fit to the first-order envelope data in both scenarios, only the Rice model generally fits the second-order statistics data accurately. For the viaduct scenario, higher RiceKfactor can be observed. The change tendency of theKfactor as a function of distance in the two scenarios is completely different. It can be concluded that the over bridges which span the railway tracks in terrain cutting scenario would affect the RiceKvalue severely.

“…The relative permittivity and conductivity of the muscle tissue are approximately 53.3 and 1.2 Sm1 respectively at 6 GHz. The transmitter and receiver are modeled either as 2.2 cm long dipole antennae(approximately half-wavelength at 6 GHz in free space) or as disc cone antennae[8]-[9], all located in close proximity to the human arm. By using this model, the transmission can be determined -spac and the antennae polarization giving the lowest the simulation is first verified by comparing theFig.…”

Ultra wideband (UWB) is an emerging technology Up to now, although a significant amount of studies have with promising applications in wireless body area networks been carried out on UWB channel propagation in wireless (WBANs). Detailed understanding of the propagation mechanism communications they are more focused towards propagation of UWB signal around human body is essential for the communvicons, nthey are more f e t rds prgations development of wearable sensors. However there are currently in indoor environment [3]-[4]. There are limited invesgations limited studies describing UWB signal propagation around onthe transmissionmechanism of UWB signal inWBAN [5]-human body. In this paper, the favorable antennae polarization [7]. For example, calculation models of transmitter and for effective transmission of signal to receiver is investigated receiver attached to an arm using the finite-difference timethrough numerical simulations. The results showed that antennae domain (FDTD) method have been proposed for clarification oriented in perpendicular polarization with respect to body .
