The underlying channel model takes for granted non frequency-selective fading but considers the e ects caused by shadowing. For such a channel model we design a simulation model that is based on an e cient approximation of ltered white Gaussian noise processes by nite sums of properly weighted sinusoids with uniformly distributed phases. In all, four completely di erent methods for the computation of the coe cients of the simulation model will be introduced. Furthermore, the performance of each procedure will be investigated on the basis of two quality criteria. All the presented methods have in common that the resulting simulation model has a completely determined fading behaviour for all time. Therefore, the simulation model can be interpreted as a deterministic model that approximates stochastic processes such as Rayleigh, log-normal, and Suzuki processes.
