Techniques of using a microphone array to determine a sound source location, the localization problem, has been studied for many years. A popular method is the so-called MUSIC (Multiple Signal Classification). There is a second type of method that tries to solve both sound separation and localization problems in one setting. The second method used for localization purpose is less known. In this study,...
This work explored two methodologies for clustering independent components (ICs) into physiological groups corresponding to maternal respiratory (MR), maternal cardiac (MC), foetal cardiac (FC), or noisy (N) activities. The methods, based on frequency content (S) or time-structure (R) analyses, were tested on 750 ICs (extracted from 25 abdominal phonograms by using single-channel independent component...
Two effective ECG beat classification methods based on signal decomposition were compared in terms of effective feature selection and noise tolerance. The HOS-DWT-FFBNN method associated with the linear correlation based filter (LCBF) provides imposing capability to select the more representative features than the IC reordering method OWSL associated with the ICA-SVM method. Both methods are insensitive...
A new method based on improved multiple signal classification (MUSIC) algorithm and independent component analysis (ICA) method is applied in this paper. In contrast with the original MUSIC algorithm, the proposed version can give good performance at lower signal/noise ratio (SNR). After estimating the frequencies accurately, the amplitudes and phases of interharmonics are calculated with ICA method...
