Abstract
The problem of parametric estimation of harmonic signals in the presence of noise and computational constraints is an important issue in many engineering fields. This technical note proposes an algorithm for frequency and bias estimation under noisy measurements. An approach for high-frequency noise rejection by switching is proposed and applied for improvement of the estimation accuracy. Efficiency of the approach is demonstrated through numerical simulations.
