Analysis of Nonstationary Characteristics for High-Speed Railway Scenarios

Abstract EN

This paper presents the analysis of nonstationary characteristics for high-speed railway (HSR) scenarios, according to passive long-term evolution- (LTE-) based channel measurements.

The measurement data collected in three typical scenarios, rural, station, and suburban, are processed to obtain the channel impulse responses (CIRs).

Based on the CIRs, the nonstationarity of the HSR channel is studied focusing on the stationarity interval, and a four-state Markov chain model is generated to describe the birth-death process of multipath components.

The presented results will be useful in dynamic channel modeling for future HSR mobile communication systems.
