A frequency-domain parameter identification method based on improved particle filtering algorithm is proposed to identify parameters of generator excitation system. The process model and measurement model of the nonlinear excitation system parameter identification are proposed, which can correct the position of each particle based on the residual and the error between the particle and the local optimal...
According to the symmetric characteristics of bispectrum, a novel feature extraction scheme, which includes the summation-at-every-column feature vector, the summation-at-every-row feature vector and their combination in a triangle area, one of the 12 symmetric areas of bispectrum, is proposed. By using One-against-One (OAO) method of multi classification of Support Vector Machine (SVM), the mean...
Subband based blind source separation (BSS) has a great potential in solving the complicated convolutive mixing problems. However, its performance is largely affected by the permutation ambiguity problem during the synthesis stage. Researchers have suggested methods to correct the permutation by using the correlation information between adjacent frequencies/subbands. In this paper, we propose an improved...
