Modeling and simulation of nonstationary land mobile satellite channels by using extended Suzuki and handover processes

A dynamic M-state model for nonstationary land mobile satellite (LMS) channels is presented. We show how the statistical properties of the proposed dynamic channel model can be adapted to the statistics of real-world LMS channels in different environments. From the dynamic M-state model, which is considered as a reference model, an efficient simulation model is derived by replacing all colored Gaussian noise processes by finite sums of cosinusoidal functions. It is demonstrated by several theoretical and simulation results that the performance of the reference model and the there-from derived simulation model are excellent with respect to the probability density function (PDF) of the fading envelope, level-crossing rate (LCR), and average duration of fades (ADF)
