Signal's taylor polynomial fingerprint extraction based on EMD and HT

Owing to complex electromagnetic environment, signal extraction is becoming more and more difficult. On account of the fact that amplifier can be fitted with Taylor series expression, Taylor polynomial is defined as signal's fingerprint for the purpose of signal recognition and classification. In this paper, firstly signal is processed by EMD and HT method in order to get signal's mathematical expression. After that, transform it into the form of Taylor polynomial so as to find out the fingerprint of signal. By means of simulation in matlab, it is confirmed that this method is viable in signal recognition and classification, that is, Taylor polynomial can be extracted from signal with Gaussian White Noise and serve as the fingerprint based on EMD and HT method.
