| Abstract: | A method of identifying different signals is given in this paper.The method is to obtain the eigenvector of signal energy by using the solution of three grade of the wavelet packets,and the to determine the two signal correlativity with the correlation coefficient of the signal energy distribution. Experimental results show that this method is more simple and effective than traditional one in identification of noise and vibration source of automobiles. |
