A rain and scintillation Ka-band channel simulator

This paper describes the implementation of a Ka-band satellite channel simulator with emphasis on the synthesis of scintillation processes. The problem becomes one of generating a given probability density function, the Moulsley-Vilar distribution, with a specified power spectral density using a Wiener model based on orthogonal Hermite polynomials for the nonlinearity. A numerical procedure is devised to calculate the filter and nonlinearity coefficients of the Wiener model. The generation of rain processes conforms to the Maseng-Bakken model.
