Research on interference suppression algorithms for short distance HF communication systems

针对传统舰船短波通信系统干扰算法存在可用频段盲点,不能快速确定近距短波的干扰问题,设计近距短波通信系统干扰抑制算法。通过电离处理方式将信号中噪声较高的部分进行处理,确定信号源,在此基础上对近距短波系统的干扰信号分类,采用干扰滤波算法,实现对短波通信系统干扰抑制。并设置实验,将传统抑制算法与本文设计的算法进行对比,主要对比2种方法的频段内盲点数据控制效果和抑制速度,实验对比结果表明,此次设计的算法能够有效对盲点数量控制,并缩短了计算时间。

Aiming at the problem that the traditional interference algorithm of short-wave naval communication system has blind spots in available frequency band and can not quickly determine the short-range interference,an interference suppression algorithm of short-range short-wave communication system is designed.The high noise part of the signal is processed by ionization method,and the signal source is determined.On this basis,the interference signal of short-range HF system is classified and the interference filtering algorithm is adopted to suppress the interference of short-wave communication system.And set up experiments,compare the traditional suppression algorithm with the algorithm designed in this paper,mainly compare the control effect and suppression speed of blind data in frequency band of the two methods.The experimental results show that the designed algorithm can effectively control the number of blind points and shorten the calculation time.
