摘要
卫星通信系统较易受到各种干扰,尤其是人为干扰,为了抑制干扰,需对信号进行正确的干扰检测。就几种常见的卫星干扰信号,对其进行Matlab仿真实验,研究不同干扰类型信号的特点,提出一种改进的CME算法用于检测干扰信号是否存在。与能量检测法和传统的CME方法相比,它具有较好的检测性能。仿真结果表明,提出的CME方法可以有效用于干扰检测。
The satellite communication systems are easy to interfere,especially suffering from contrived jamming. To restrain interference,interference signals need to be correctly detected. In this paper,different interference signals in satellite communication commonly used are chosen,and under simulation experiment to research their characteristic. An improved CME algorithm is presented to be used to detect the existence of interference signals. Compared with energy detection algorithm and traditional CME algorithm,the improved CME algorithm has a good detection performance. Simulation results show that the method can be used to detect interference efficiently.
