基于盒子维数和最大Lyapunov维数的瞬态信号特征提取
Transient signal feature extraction based on box dimension and maximum Lyapunov dimension
摘要
Abstract
Cognitive radio is one kind of wireless communication technology,which effectively improves the spectrum effi⁃ciency by the way of wireless spectrum sensing. Besides of varieties of security issues of the traditional wireless communication, it also has some new problems,such as Primary User Emulation(PUE) attack. This paper proposes that the transient signal characteristics extraction based on the fractal dimension protects the PUE attack from the cognitive wireless networks,and then extracts the fractal dimension of wireless transmitter through experiments,which provides reliable characteristic parameters for the next signal recognition to prevent the attack of PUE.关键词
