Abstract :
This letter presents a new formulation of the extended Kalman filter (EKF) for use in frequency tracking. A brief summary of previous EKF approaches is given and the new approach detailed. Simulation studies of the standard and new algorithms show that a significant improvement in tracking and threshold performance is achieved.
