Simulation of Wide Band Channels with non-separable scattering functions

In this paper a new and constructive method useful to simulate Wide Band Channels with non-separable scattering function via the filtering approach is provided. This method is based on the approximation of the Channel by the eigenfunctions taken from the Karhunen-Loève expansion of the Channel´s. ensemble autocorrelation function at Δt=0. Channel realizations are performed via the filtering of an independent gaussian random process vector by some filter matrix, which is obtained from some manipulations of the correlation statistics of eigenfunctions. An example to clarify this proposal is also presented.
