Abstract :
In this paper a computer simulation model for a land mobile radio fading channel is presented. The model assumes non frequency-selective fading but takes into consideration the effects caused by shadowing. The simulation model is based on an efficient approximation of filtered white Gaussian noise by a finite sum of weighted sinusoids with equally distributed phases. Two completely different methods for the computation of the coefficients of the simulation model are discussed. The design of a fading channel model by one of the presented methods leads always to a simulation model that is completely determined for all time, and therefore, it can be considered as a deterministic model that approximates a stochastic process
