基于FPGA光纤扰动检测算法的设计与实现

目前光纤通信应用日益广泛,通信的保密性也变得越来越重要.光纤扰动检测技术,是保密光通信和光纤侵入预警等光纤应用系统的核心技术,通过检测光纤中传输信号的强度变化,分析出是否有外界侵入.当前常用的扰动检测方法,存在系统构架庞大、应用模式狭窄、速度慢等缺点.利用FPGA并行处理结构及丰富的逻辑资源等特点,设计了基于FPGA纯...

Design and Implementation of Fiber Intrusion Detection Algorithm Based on FPGA

With the development of fiber communication,the confidentiality has become increasingly important. The technology of intrusion detection is the key step within secure communication and distributed optic-fiber intrusion early warning system.When the optical fiber is disturbed,the light through the optical fiber will change in the light intensity,by detecting the changes,the outside intrusion can be detected.The usual methods of intrusion detection have some shortcomings,such as the larger system,the narrower...
