A new theoretical propagation model for wideband fading channel simulation in mobile radio environments is presented. It is based on a path model which produces scattered waves according to Poisson process. The typical properties of transmission characteristics deduced from the theoretical and experimental studies are taken in the model. Using the propagation model, an analytical method for the near-far problem of CDMA in mobile radio environments is proposed. An example of the analysis by means of a simulation is also presented.
