In a recent article we have introduced and used the complex fractional wavelet for QRS complex detection in ECG signal. This complex fractional wavelet is derived from the Cole-Cole distribution which is widely used in the modeling of dielectrics by a fractional power pole. This work presents an extension of QRS detection scheme using the complex Morlet wavelet function. It consists of using the real...
Depolarization of the myocardial cells of the left and the right ventricles via the irregular but self-similar pattern of branching of the His-Purkinje tree produces the QRS complex on the surface electrocardiogram. The analysis of the power spectrum of the QRS complex has shown that it has the inverse power law or fractal behavior. This fractal behavior has been modeled in the frequency domain by...
In this paper special focus is given to the application of fractional spline wavelet functions to solve electromagnetic scattering problem via numerical techniques. In this work the numerical technique used is the well known Moment method and the wavelets are used as basis function, and the electromagnetic scattering problem chosen here is a rectangular horn, considered to be perfect conductor. In...
In this paper a simple and an efficient approach for approximating the fractional delay operator z-a (0 <; a <; 0.5) using digital infinite impulse response (IIR) filters is proposed. In this technique, the coefficients of the closed form digital IIR filter derived for the approximation of the fractional delay operator, in a given frequency band, are based on the approximation of fractional...
In a recent paper we have introduced and used a real fractional wavelet for the detection of the QRS complex in ECG signal. This fractional wavelet is the second derivative of the Cole-Cole distribution which is widely used in the modelling of dielectrics by a fractional power pole. This work presents a QRS detection scheme using a complex fractional wavelet function. The absolute value of this wavelet...
In this paper we examine the use of fractional wavelet for the detection of QRS complex in ECG signal. The wavelet we used is the second derivative of the Cole-Cole distribution that is widely used in mathematical modelling of dielectrics and viscoelastic dynamics and it's related to the fractional power pole (FPP). With the multiscale feature, the wavelet transform (WT) has provided more ability...
