| Abstract: |
| The capacity of CDMA satellite communication system is analyzed,and the system mathematics model of the CDMA satellite communication system capacity is provided from the viewpoint of system.The system capacity,the relationship between user number and spread spectrum gain,anti-jamming performance,saturated power of satellite emitter,etc.is analyzed quantitively.The analysis result of the CDMA satellite communication system provides a reference for people to choose and design satellite communication systems. |
| Key words: satellite communication,CDMA,spread spectrum,capacity analysis |
