小波分析在通讯光纤故障诊断系统中的应用研究

摘要

小波分析理论在信号去噪、信号奇异值分析等方面有显著的优势。通过Matlab小渡变换工具箱仿真实现曲线信号的降噪、OTDR曲线分析，并通过实验确定光纤故障诊断系统中OTDR事件点。%The theory of wavelet transform has a distinct advantage on the signal denoising,singularity analysis and fault diagnosis.By the Matlab wavelet toolbox,Simulation,actualize the curve signal noise reduction,OTDR trace analysis,and determine OTDR event in o
