The Recognition of Vibration Sensor´s Signals Based on ICA

Vibration sensor´s signals are collected from wireless perimeter intrusion monitoring device named NETCORE-1000 which is developed by our research group. The computer simulation (respectively using four kinds of typical algorithms) for those signals are experimented after the basic model of independent component analysis, independence criterion and the four kinds of typical algorithms are described in this paper. Experimental results show that independent component analysis method has a very strong ability to Blind Source Separation. Thus a new and effective signal processing tool is provided for the study of recognition of intrusion signals in the field of perimeter security.
