摘要
智能天线技术可以极大地增强卫星通信系统的抗干扰性能。讨论应用于卫星移动通信终端的智能天线技术,提出了利用智能天线技术的卫星移动通信终端的两种可能的系统实现方案。从计算成本及干扰抑制性能的角度对它们做了初步的比较,仿真结果表明采用这两种实现方案的卫星移动通信终端可以有效抑制下行链路存在的干扰,提高输出信干噪比,取得较为满意的干扰抑制效果。
The technique of smart antenna is able to enhance the performance of anti - jamming in the area of satellite communication system. In this paper, we introduce the application of this technique in mobile satellite communication terminal and two possible system implementation schemes of mobile satellite communication terminal using the smart satellite antenna technique and we compare these two schemes preliminarily according to computation cost and the performance of interference rejection. The results of simulation indicate that the terminal adopting these two schemes can restrain the interference existing in downlink effectively, improve the output SINR and obtain the satisfying effect of interference rejection.
