These features support better attachment of it to the subject's body and hence get less affected by the slow motion of the subject. However, noise generated due to the footsteps, while walking, contaminates the SCG signal. Therefore, in this paper, a novel method is proposed to remove these contaminations from the SCG signal. A three-axis accelerometer was attached to the chest wall such that heart sound components are reflected in the z-axis while the motion noise due to footstep will be seen in the x-axis. To remove the noise components from the heart signal (z-axis), the location of footsteps from the x-axis are identified and the corresponding components from the z-axis are removed. After noise removal fundamental heart sounds (FHS), S1 and S2, are identified using Otsu's threshold method. The obtained results show that the proposed algorithm outperforms the state-of-the-art methods. It efficiently removes most of the contamination due to footsteps and identifies the heart sound components.","PeriodicalId":88900,"journal":{"name":"International Conference on Digital Signal Processing proceedings : DSP.

For the PCG signal, Discrete Wavelet Transform (DWT) based denoising method has been used extensively due to its good performance. However, the performance of this method depends on the threshold value and the way to apply it on the wavelet coefficients. Therefore, in this paper, an adaptive method is proposed to estimate the threshold value for the shrinking of the wavelet coefficients of the PCG signal. For this purpose, a new statistical parameter is obtained by incorporating medical domain knowledge about the PCG. The threshold value is estimated based on the statistical analysis of the wavelet coefficients and the present level of noise. Further, to overcome the issues related to existing threshold functions, soft and hard, new threshold functions, mid and non-linear mid are presented. The proposed method is applied to the PCG signal contaminated with simulated white Gaussian noise, red noise, and pink noise. The obtained results of the proposed method are compared with the results of state-of-the-art methods and they show the superiority of the proposed method.","PeriodicalId":88900,"journal":{"name":"International Conference on Digital Signal Processing proceedings : DSP.

We have introduced an improved piloted adaptive notch filter with transient suppression and a higher probability of correct steering direction. The concept of variable pole-radius has been employed to significantly reduce the transient effect and improving the directional properties of the notch. Computer simulations demonstrate the excellent performance of the variable-pole radius piloted notch filter to significantly outperform the traditional piloted notch filter with respect to the speed of convergence and steady-state mean square error (MSE).","PeriodicalId":88900,"journal":{"name":"International Conference on Digital Signal Processing proceedings : DSP.
