Abstract:

This paper puts forward a two-state land mobile satellite channel model on the basis of Markov chain. Transfer between the two states is described as Markov process, and probability density function of receiving signal envelope in each state follows the Loo distribution. Statistical characteristic of first order and second order is attained via doing mathematic modeling and simulation analysis of the process, and are compared with that of the measured data in the same environment. The simulation result shows that in various environments, the statistical characteristics of the two-state land mobile satellite communication channel model based on Markov chain are close with that of the measured data, which proves that the constructed channel model can be used to simulate the satellite mobile communication channel in practical environment. It not only provides an effective platform for the evaluation of mobile communication technology and the planning of communication system in future, but also has a wide applicability.

Key words: mobile satellite communication, two-state channel model, Markov chain, fading statistics
