摘　　要：对基于码分多址(CDMA)体制的通信卫星系统及其容量进行了分析,从系统的角度,提出了CDMA体制的通信卫星系统容量的数学模型。定量分析了用户数量与系统的扩频增益、抗干扰能力指标、卫星转发器饱和功率等的关系,容量分析的结果可供人们在选择和设计通信卫星系统时参考。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.
