Abstract
The problem of estimating instantaneous frequency of a nonstationary complex sinusoid (cisoid) buried in wideband noise is considered. The proposed approach extends adaptive notch filtering algorithm with a nontrivial performance assessment mechanism which can be used to optimize frequency tracking performance of the adaptive filter. Simulation results confirm that the proposed extension allows one to improve accuracy of frequency estimates considerably, especially in nonstationary conditions.
