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。
Satellite system capacity will be affected by thermal noise and co-channel interference and loss. According to the proposed method of calculating interference factor, the relationship between interference factor and system available channel quantity is analyzed. A typical channel is extracted and the link parameters are estimated. The available channel capacity and system communication capacity , Which provides a theoretical basis for the related capacity control strategy formulation. A typical channel is configured and the link parameters are simulated. The results show that the user requirements of the satellite communication system can be satisfied under the condition of reasonable interference factor and signal-to-noise ratio.
