| Abstract: | Wireless channel in satellite mobile communication is a typical fading channel,and its existing effects of shadowing, multi-path and Doppler heavily affect the system performance, or it even load to communication outage in some serious cases. By cooperating different nodes, the cooperative communication technology could enjoy the supriority of spatial diversity and effectively resist the channel fading, thus improve the communication quality. Aiming at the application of cooperative communication technology in satellite mobile communication, the typical application ideas and modes are proposed and the corresponding simulation and analysis also done. Simulation results indicate that the satellite mobile communication system could be effectively improved by introducing the cooperative communication technology into satellite mobile communication. |
