摘　　要：无线信道仿真器,是对真实信道环境的拟合,可以提高通信系统的研发和测试效率,具有很强的现实意义。Lutz模型是一种非稳态信道,能够在良好信道状态和不良信道状态之间进行切换,并有效描述信道的变化特征。设计了一种基于Lutz模型的频率选择性信道,在FPGA中采用分模块进行实现,然后使用Modelsim和Maltab等工具进行验证,仿真结果表明无线信道仿真器的FPGA实现,满足信道特征的统计特性,可直接用来测试无线通信系统。The wireless channel simulator is a fitting of the real channel environment. It can improve the research and development（ RD） and testing efficiency of communication system,and has very strong practical significance. Lutz model,a non-steady channel,can switch between good channel state and bad channel state,and describe the changing characteristics of channel effectively. This paper describes the design of a frequency selective channel based on Lutz model,used in FPGA module,and then uses Modelsim and Maltab tool to verify the implementation of FPGA. The results show that the FPGA implementation of wireless channel simulator can meet channel statistical characteristics,and be directly used to test the wireless communication system.
