Abstract: In this paper, a new closed-form solution is presented for the parameters computation of the multiple uncorrelated Rayleigh fading models. The new model employs random Doppler frequency wobble for all individual sinusoids based on the method of exact Doppler spread (MEDS). And the second-order statistics of the new model match the desired ones exactly better than the generalized method of exact Doppler spread (GMEDS) even if the number of sinusoids is a single-digit integer, and compare to the original MEDS the new model has random Doppler frequency, ensure the unification of uncorrelation and ergodicity of fading channels; The proposed methods are useful for the design of simulation models for diversity-combined Rayleigh fading channels, frequency-selective channels, and multiple-input multiple-output (MIMO) channels. Moreover, the random wobble amplitude can be set according to project needs, simulation pictures show that this new model is simple and effective.
