Comparative Analysis of EMD and VMD Algorithm in Speech Enhancement

Ram, Rashmirekha; Mohanty, Mihir Narayan - In: International Journal of Natural Computing Research (IJNCR) 6 (2017) 1, pp. 17-35

Signal enhancement is useful in many areas like social, medicine and engineering. It can be utilized in data mining approach for social and security aspects. Signal decomposition method is an alternative choice due to the elimination of noise and signal enhancement. In this paper, two different...

The study of the intermittency test filtering character of Hilbert–Huang transform

Li, Helong; Yang, Lihua; Huang, Daren - In: Mathematics and Computers in Simulation (MATCOM) 70 (2005) 1, pp. 22-32

A new filtering method for data with intermittency problem is proposed in this paper. In this new method, the original data is pretreated using wavelet method to avoid the mode mixture in the subsequent empirical mode decomposition (EMD) procedure. We make use of the approach to extract...
