The second order recursive maximum likelihood algorithm is used to estimate the sinusoidal frequencies. It is suitable for real-time operations because only 13 multiplications, 14 additions and 1 division are required in each iteration. After adaptive notch filters have converged, the simplified recursive least square algorithm is then used to compute the amplitudes and phases of sinusoids quickly. The error surface analysis indicates that our scheme is unimodal and results in guaranteed convergence. Extensive computer simulations are also included to demonstrate its performance. © 1994. |
