Abstract. Currently, the reliability of wireless channel simulation is poor, and it cannot provide the interface for the actual physical equipment. Rayleigh fading channel model is used as the theoretical model in this paper, proposed a model based on shaping filter method and easy to implement for FPGA hardware. The model uses a computer to realize the shaping filter to reduce the consumption of the FPGA chip resources; linear interpolation method to achieve the Doppler frequency shift, Rayleigh fading. Test results show that the output of the hardware simulator fading characteristics consistent with the theoretical value, it can be used for wireless communication system simulation test.
