摘要
在考虑了高速铁路地理环境和高速等因素的基础上,综合考虑了多普勒效应和多径效应的影响,针对现有小尺度衰落无线信道模型的不足,应用了一种适合高速铁路环境下的无线信道模型。在Jakes信道仿真器的基础上,建立高速铁路环境下的无线高速信道模型。应用Matlab仿真软件对信道多普勒功率谱密度和信道包络进行仿真,说明信号建模的合理性。仿真结果与理论分析吻合,从而说明了模型的有效性。
In consideration of the geographical environment and high speed of the high-speed railway,and for the inadequay of existing small-scale fading wireless channel,an innovative mobile radio channel model is proposed in integration of those factors such as doppler frequency shift and multipath.The channel doppler power spectral density and signal envelope of the model is simulated with Matlab software.The simulation results are identical with those of theoretical analysis.This indicates that this proposed model is feasible and effective.
