摘　　要：卫星系统容量会受到热噪声和同频干扰影响而损失。根据提出的一种计算干扰因子的方法,分析了干扰因子与系统可供信道量的关系,提取了典型的信道并对链路参数进行估算,分别得到了系统的可供信道量和系统通信容量,为相关的容量控制策略的制定提供了理论依据。配置了典型的信道,对链路参数进行仿真,结果表明在干扰因子和信噪比合理的情况下,可以满足卫星通信系统的用户要求。The capacity of Satellite System would be damaged by hot noise and same frequency. Based on a calculation method of interference factor, the relationship between the interference factor and the capacity of active channels is analyzed. The channel and link parameters are extracted and estimated, thus obtaining the number of available system channels and the system traffic capacity and providing theoretic basis for the establishment of related capacity control strategy. In combination with the characteristics of Satellite System and with typical channel and link parameters, the simulation shows that, under the condition of reasonable interference factor and SNR, the customer requirements of satellite communication system can be satisfied.
