Sparsity and Multi - resolution BSS Method for Harmonic Signal Extraction
نویسندگان
چکیده
Using the sparsity property in the frequency domain of harmonic signals, this paper gives a harmonic extraction algorithm based on multi-resolution blind source separation (BSS) method. After the general and detailed definition of the multi-resolution BSS model is given, the wavelet packet decomposition based multiresolution BSS algorithm for harmonic signal extraction is constructed in detail. Some simulations of the proposed algorithm are exhibited in the simulation part to demonstrate the validity of the method. At last, we discuss the impact of multiresolution BSS research and outline potential future research directions and applications. Copyright © 2014 IFSA Publishing, S. L.

Extraction of Sensory part of Ulnar Nerve Signal Using Blind Source Separation Method
A recorded nerve signal via an electrode is composed of many evokes or action potentials, (originated from individual axons) which may be considered as different initial sources. Recovering these primitive sources in its turn may lead us to the anatomic originations of a nerve signal which will give us outstanding foresights in neural rehabilitations. Accordingly, clinical interests may be r...
متن کاملEstimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power
Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...
متن کاملEEG Based Brain Computer Interface Hand Grasp Control: Feature Extraction Method MTCSP
Brain-Computer Interfaces (BCIs) are communication systems, which enable users to send commands to computers by using brain activity only; this activity being generally measured by Electroencephalography (EEG). BCIs are generally designed according to a pattern recognition approach, i.e., by extracting features from EEG signals, and by using a classifier to identify the user’s mental state from...

متن کاملBlind Source Separation: the Sparsity Revolution
Over the last few years, the development of multi-channel sensors motivated interest in methods for the coherent processing of multivariate data. Some specific issues have already been addressed as testified by the wide literature on the so-called blind source separation (BSS) problem. In this context, as clearly emphasized by previous work, it is fundamental that the sources to be retrieved pr...
