A new approach based on conventional propagation graph channel modeling was proposed to haracterize the wireless channel in non-light of sight (NLOS) tunnel scenarios. The scattering points are regarded as several points sets, which are different from the propagation-graph theory, then the transfer probability among sets is introduced to adjust the channel impulse response (CIR) taps. The advantage...
The non-stationary properties based on Markov chains are proposed to describe the wireless propagation mechanism of High Speed Railway (HSR) under viaduct scenarios. This Markov modeling method reveals the statistical behaviors of the persistence process corresponding to a resolvable multipath component. Based upon the channel measurement on Beijing-Tianjin HSR at 2.35 GHz, the transition probability...
Based on the realistic channel measurement on High-Speed Railway (HSR) in viaduct scenarios at 2.35 GHz, the dynamic evolution of multipath components is investigated from the birth-death process point of view. Due to the distinction in the amount of resolvable multipath signals, the channel is divided into five segments and can be completely parameterized by several sets of statistical parameters...
