摘要
由于传统电子通信双频干扰检测方法在实践中经常出现漏检现象,且漏检双频干扰数量较多,因此提出基于伪随机特征码的电子通信双频干扰检测研究。结合时间序列分析技术统计并分析电子通信传输的异常流量信号,区别未受到双频干扰影响的正常通信流量信号和双频异常流量信号。利用伪随机特征码判断待测信号的具体长度,根据电子通信信号的短时性特征,识别电子通信双频干扰信号。针对检测到的双频干扰建立电子通信双频干扰抑制方案,以完成基于伪随机特征码的电子通信双频干扰检测。实验证明,设计方法漏检双频干扰数量少于传统方法,适用于电子通信双频干扰检测。
Because the traditional dual-frequency interference detection method of electronic communication often appears the phenomenon of missing detection in practice,and the number of missed dual-frequency interference detection is large,so this paper proposed the research of dual-frequency interference detection based on pseudorandom characteristic code.Combined with the time series analysis technique,the abnormal traffic signals transmitted by electronic communication are counted and analyzed,and the normal traffic signals which are not affected by dualfrequency interference are distinguished from the abnormal traffic signals which are not affected by dual-frequency interference.The specific length of the signal to be measured is determined by using the pseudo-random characteristic code,and dual-frequency interference signals are identified according to the short-time characteristics of electronic communication signals.Aiming at the detected dual-frequency interference,a dual-frequency interference suppression scheme for electronic communication is established to complete the detection of dual-frequency interference based on pseudo-random characteristic code.The experimental results show that the design method is less than the traditional method and is suitable for the detection of dual-frequency interference in electronic communication.
