It is found that at high and medium signal-to-noise ratio, the OPM performs quite like MUSIC with a complexity reduced by the ratio of the number of sources to theNumber of sensors.Expand

An improved QRS (Q wave, R wave, S wave) complex detection algorithm is proposed based on the multiresolution wavelet analysis, which presents considerable capability in cases of low signal-to-noise ratio, high baseline wander and abnormal morphologies.Expand

It is shown that the propagator method, used for the multiple source direction of arrivals estimation may have a theoretically asymptotical high resolution power.Expand

A novel method based on time-frequency analysis in conjunction with a threshold evaluated on Renyi entropy for the segmentation and the analysis of PCG signals and permits elucidating and extracting useful features for diagnosis and pathological recognition.Expand

This paper applies results from studying autoregressive filters to prove some extremal properties of stable filters such as the maximum value of the components of the regression vector or themaximum value of its norm.Expand

A simple procedure for eliminating the classical epsilon -method introduced by the Routh-Hurwitz test is given. The procedure extends the construction of the Routh table in the special case of… Expand

This result allows us to introduce generalized time-frequency distributions for studying signals having a polynomial phase and a constant amplitude in order to determine the degree and the coefficients of the corresponding phase.Expand

The goal is to perform blind identification of a linear-quadratic mixture of independent and circular random components using the singular value decomposition of a third-order output cumulants matrix.Expand

A new version of the PM referred to as the orthonormal propagator method (OPM) is proposed, which shows that at high and medium signal-to-noise ratio, the OPM performs like MUSIC with a complexity reduced by the number of sources to thenumber of sensors ratio.Expand
