Research on the Use of the energy spectral anaysis method base on the eigenvector in FSK Signal Detection System
Eng M · Control & Automation · 2007
In this article ,first of all, we present the problem of identifying the little signal of the short railway,then analyse the char-acters of the FSK signal .We use the energy spectral analysis method which base on the eigenvector to compute the upper and lower side frequencies, and detecting the little signal of the short railway.The simulation results show that this method works out a correct solution to the problem.
