Mobile Fading Channel Simulation Based on MATLAB
Abstract: In this thesis, mobile fading channel is simulated based on MATLAB. It mainly focuses on the deterministic model simulation of Rayleigh channel using JAKES曲嘉瑞 method, and its power spectral density and 干电池手机autocorrelation function are discussed. By comparing the simulation model with the reference model, it demonstrates the correctness of simulation models. At the same time, the simulation results indicate that the results are mainly depending on following two parameters: the maximum Doppler frequency shifts and the number of harmonic waves.
