Abstract: 

In the fifth generation (5G) wireless communication, high-speed railway (HSR) communication is one of the most challenging scenarios. By adopting massive multi-input multi-output (mMIMO) technology in HSR communication, the design of the underlying communication system becomes more challenging. Some new channel characteristics must be studied, such as non-stationarity in space, time and frequency domains. In this paper, two models are established for the two states of HSR at rest or in motion. When the train is stationary, a three-dimensional (3D) stationary channel model based on the single-ring distribution of the scatterers is established for a uniform planar array in a stable propagation scene. When the train is moving, in order to describe the non-stationary characteristics of the channel, a geometric random non-stationary channel model based on a cylinder scattering model is established by introducing the birth and death process of the propagation path and time-varying characteristics of the channel parameters. Moreover, a time evolution algorithm for time-varying channel parameters is proposed, and a modularization study of key parameter update algorithms is conducted, including the geographical location parameters of the transceiver and the scatterer, the number of effective propagation paths, and the delay. Finally, the antenna array response and spatial correlation matrix are derived for the proposed 3D channel model. The influence of the number of antennas on beam directivity is mainly studied, also the influences of parameters such as the scatterer distribution radius, antenna height, azimuth, and antenna element spacing on the eigenvalues of the correlation matrix are analyzed.

Instructions: 

With the rapid development of information globalization, wireless communication has penetrated into all aspects of people's lives. It is expected that by 2020, there will be a fifth-generation (5G) wireless communication system with ultra-high user experience data rate, ultra-high connection density and ultra-high power [1]. As a typical application scenario of 5G communication, in recent years, high-speed railway (HSR) communication scenario have received widespread attention. A large number of HSR users require a huge amount of communication data, which far exceeds the capacity of the current HSR communication system. HSR wireless communication systems also face various challenges, such as frequent handovers, large doppler frequency shifts, and rapidly experiencing different scenarios [2-5].
