摘要：提出了一种以FPGA为实现平台的Rayleigh衰落信道模拟器设计方法。该模拟器采用基于正弦波叠加法的改进Jakes仿真模型,其统计特性与Rayleigh衰落信道吻合度较好。该模型的定点仿真和模拟器的仿真实验结果表明,信道模拟器能较好地模拟Rayleigh衰落信道的特性。
A design scheme of FPGA-based Rayleigh fading channel simulator is proposed in this paper,which adopts an improved Jakes simulation model based on the sum-of-sinusoid method.The statistical characters of the proposed model have better goodness of fit with those of Rayleigh fading channels.It is shown from both the fixed-point simulation of the model and the experimental results of the simulator that the proposed simulator can attain better performances in simulating Rayleigh fading channels.
