| Abstract: | This research proposes a new hybrid Suzuki - Corazza model based on an integration of the Corazza mod- el and the Suzuki model, in which two independent Lognormal random processes are under the influence of the LOS signal and the multi - path signals, respectively. It gives a model of simulation diagram based on coloured Gaussian random processes, and the derivation process of power spectral density function, the autocorrelation function, prob- ability density function （PDF） and the cumulative distribution function （CDF） in detail, as well as the figures of the comparison between the theory and the simulation of the probability density function and cumulative distribution function. There is a good consistence between the simulation and the analytical results. |
