Abstract:

In light of wide range signal changes in the mobile satellite channel,the cooperative communication technology is introduced into the satellite communication to obtain better anti-fading performance and higher diversity gain.The paper proposes the models of the cooperation between satellites and the models of the cooperation between users.The system bit error rate performance when cooperation occurs between satellites is simulated,which shows that the proposed cooperation scheme decreases the bit error rate and the system performance is improved obviously.

Key words: cooperative communication;cooperative strategy;diversity gain;satellite mobile communication
