Shaping Filter Method, Jakes Simulation Model and Its Multiple Improved Methods

This work begins with analyzing the statistical characteristics of Rayleigh fading channels and presents the Clarke model based on this foundation. It then proposes simulation methods including the shaping filter approach, Jakes simulation model, and various improved versions. The software implementation process of these simulation models is elaborated, with computer simulations performed using MATLAB. The simulation results demonstrate high matching accuracy between the proposed models and theoretical curves, effectively simulating wireless fading channels through detailed signal analysis.
