Abstract

Channel modeling and its simulation method is a difficult point of high-speed train mobile communication system design. At the same time, there are still some researches on IMT-A time-varying channel modeling for high-speed train mobile communication. Aiming at the above challenges, this paper presented a modeling method based on IMT-A channel with high-speed train mobile with time-varying parameters. Firstly, for the urban macro-cell(UMA) scene of IMT-A, this paper designed a Markov process to simulate the number of time-varying clusters, and then derived the expression of the channel parameters with time, including the delay, power, angle and reach angle, and got the channel impulse response(CIR). Secondly, it analyzed the time-varying space-time cross-correlation function(CCF), time-varying auto-correlation function(ACF) and stationary interval of channel. Finally, it simulated the statistical properties of the proposed channel model, which proves the non-stationarity of the model and the non-stationarity of the high-speed train channel, and proves that the proposed channel model can be used to simulate the feasibility of high-speed train channel.
