摘要
通过检测实例对传统频谱干扰检测、实时频谱干扰检测、扫频干扰检测的原理和特点进行对比分析,并在此基础上提出基于服务质量的在线干扰检测方法,重点对联动分析技术、阻塞干扰自动识别、互调干扰自动识别和频谱模型识别技术进行研究。根据该检测方法研制的干扰检测系统在GSM-R网络及LTE-R网络干扰检测中取得了良好效果。
This paper examines the principles and characteristics of traditional spectrum interference detection, real-time spectrum interference detection and sweep-frequency interference detection using comparative study and real-life examples. Further, it puts forward an online interference detection method based on quality of service, focusing on linkage analysis technology, automatic identification of blocking interference, automatic identification of intermodulation interference and spectrum model recognition technology. The interference detection system developed on the basis of this detection method has achieved good results in the interference detection of GSM-R network and LTE-R network.
