The paper proposes a local linear-periodogram-Kalman filtering (LL-P-KF) hybrid algorithm.Firstly
a local linear method is established;secondly
the periods of sinusoidal signal are detected from modeling error by using periodogram;finally
the sinusoidal signal is recovered from the error by using Kalman filtering.Simulation results show that the LL-P-KF hybrid algorithm has better recovery results.
