Recursive estimation of linearly or harmonically modulated frequencies of multiple cisoids in noise

• Recursive estimation of parameters of linearly or harmonically frequency modulated sinusoidal signals is considered. The algorithms simultaneously separate the measured signal to individual components and update signal parameters using estimated phase differences. The main advantages of the proposed algorithms over standard tracking schemes such as e.g. the adaptive notch filter is zero asymptotic bias (zero tracking delay) in estimating of the instantaneous frequencies
