The novelty and the contribution of this paper consists of applying an iterative joint singular spectrum analysis and low-rank decomposition approach for suppressing the spikes in an electroencephalogram. First, an electroencephalogram is filtered by an ideal lowpass filter via removing its discrete Fourier transform coefficients outside the wave band, the wave band, the wave band, the wave band and the wave band. Second, the singular spectrum analysis is performed on the filtered electroencepha...

This paper proposes a joint empirical mode decomposition and singular spectrum analysis based pre-processing method for performing the blood glucose estimation. Here, both the near infrared signals and the electrocardiogram signal are acquired from a wearable non-invasive blood glucose estimation device. For the empirical mode decomposition based pre-processing method, the intrinsic mode functions are selected based on the correlations between the intrinsic mode functions and the acquired near i...

This paper proposes to employ the discrete cosine transform (DCT) to perform the empirical mode decomposition (EMD) based hierarchical multiresolution analysis. This can simplify the implementation because all the signals are real valued. In this paper, the intrinsic mode functions (IMFs) in the first level of decomposition are obtained by applying the conventional EMD to an electrocardiogram (ECG). Then, the first IMF is further decomposed. More precisely, the zeros are inserted to the first IM...

This paper considers the designs of the periodic window functions in the filter window banks. First, the filter window bank with the constant synthesis periodic window functions is considered. The total number of the nonzero coefficients in the impulse responses of the analysis periodic window functions is minimized subject to the near perfect reconstruction condition. This is an \begin{document} L_0 end{document} norm optimization problem. To find its solution, the \begin{document} L_0 en...
