Abstract :
We discuss three methods for the computation of the model parameters of spatial channel simulators basing on Rice´s (1944, 1945) sum of sinusoids. Each method is universally described and can in principle be applied to the modelling of any type of scattering object with given spatial characteristics. However, examples illustrating the procedures are presented for a Laplacian scattering object only. The performance of each procedure is investigated with respect to important spatial characteristic quantities such as the spatial cross-correlation function (SCCF), the mean angle of arrival (AOA), and the angular spread.
