摘　　要：针对常用的无线信道模型主要作用于点频或者窄带信号,不能满足宽带信号传播特性模拟的问题。在窄带信道模型的基础上,提出了一种宽带无线信道仿真的建模思路,通过在大尺度衰落仿真建模过程中引入宽带特性,并与频率选择性小尺度衰落模型相结合,实现宽带无线信道的建模和仿真,满足了宽带信号传播特性模拟的需求,对于宽带无线信道建模仿真具有一定的参考意义。The commonly used wireless channel model is mainly for point-frequency or narrow-band signals,and can’ t meet the requirements of wideband signal propagation characteristics simulation. In order to solve the problems, this paper proposes a wideband wireless channel simulation and modeling idea based on narrow band channel model. The modeling and simulation of wideband wireless channel are implemented by introducing wideband characteristics in the large-scale fading simulation and modeling process and combining with the frequency selective small-scale fading model. The results satisfy the requirements of wideband signal propagation characteristics simulation, which can provide references to wideband wireless channel modeling and simulation.
