Abstract :
A notch filter is proposed for single complex frequency estimation problem. It is represented as state-space equation model, which has good stability. A cost function is presented, and by applying Gaussian-Newton type recursive prediction error based method, a stable and efficient online frequency estimation algorithm is derived. Finally, the simulations are performed, and the results show that the proposed algorithm has fast convergence and high estimation accuracy.
