An efficient deterministic simulation model for land mobile LEO satellite channels

This paper proposes a simple and efficient deterministic simulation model for land mobile LEO satellite channels. A stochastic process, Rice-lognormal process, which is the product of a Rice and a lognormal process is used to model land mobile LEO satellite channels. The in-phase and quadrature components describing the Rice process are assumed to be uncorrelated for simplifying the structure of the computer simulation model. The restricted Jakes Doppler power spectral density (psd) function is incorporated into the model to ensure that it will be appropriated for evaluation of a digital beamforming (DBF) antenna. The performance of the model is validated by comparing its probability density function (pdf), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades (ADFs) with measurement results.
