This paper briefly describes the Rayleigh fading channel and introduces two simulation methods: Mean Squared Error Method (MSEM) and Exact Doppler Spread Method (MEDS). Rayleigh fading channel simulation is carried out based on Matlab, and simulation signals and analysis results are presented. The results show that the simulation model matches the theoretical curves well and can effectively simulate wireless fading channels. These research findings have practical significance for the design and performance analysis of mobile communication systems.
