摘要
为了解决LTE网络干扰排查工作缺乏有效排查手段以及故障定位困难的问题,采用了干扰波形特征分析方法,通过分析PRB干扰扫描数据,研究了干扰类型匹配算法,并提出了干扰波形对比干扰特征库的解决方案。经过实验证明,干扰类型匹配算法能够快速准确地判断出干扰源的类型,由于其可软件化的特征,非常适合在网络公司大面积推广。
To solve the problem of shortage on methodologies of LTE interference clearance and identiifcation, the author of this article used interference graph characteristics analysis method, studied interference categorizing matching algorithm by analyzing PRB interference scanner data, proposed a solution matching interference graph to interference characteristics database. It is veriifed by experiments that interference categorizing matching algorithm can identify the interferer swiftly and accurately. It is fit for broad application in network companies due to its programmability.
