Impulsive noise and interference are always present in the environment in addition to additive white Gaussian noise that corrupts the measured data. In such cases, conventional adaptive estimation algorithms based on least squares error cost function provides poor performance in estimating the optimum parameter. In order to alleviate this shortcoming, a robust diffusion strategy based on QR decomposition...
Hybrid fast Fourier transform Adaptive LINear Element (FFT-ADALINE) algorithm for fast and accurate estimation of harmonics is proposed in this study. The FFT method can perform fast conversion from time domain to frequency domain, but it cannot respond immediately to any change of the measured harmonics due to the utilisation of buffer. Meanwhile, ADALINE has better capability to respond immediately...
