Abstract :
In this paper, Amplify-and-Forward (AF) strategy of cooperative diversity in the low Earth orbiting (LEO) satellite mobile communication system was presented to reduce the influence of multi path fading and shading. First, the feasibility of the AF in constellation satellite communication system was analyzed, then the system model was given and predigested to the typical three points model, Some typical mobile satellite channels were selected to analyze and simulate. The results show that the pervious probability of communication and the performance of system was improved and the power of the terminal was decreased.
