A novel approach for frequency estimation of one-dimensional harmonics in multiplicative and additive noises is presented. To alleviate the resolution limitation of the traditional cumulant-based algorithms, group delay (GD) function is utilized. In this new approach, GD is applied to the 2<sup>nd</sup> order time-varying cumulants of harmonics in complex(More)
A novel regression model combining least squares support vector regression (LS-SVR) with multi-scale wavelet kernel and particle swarm optimization (PSO) was presented in this paper, and applied to the approximation of non-stationary dataset and those continuous functions polluted by strong noise. Support vector kernel function with the multi-resolution(More)
