摘要：

This paper investigates the use of gradient-based algorithms with infinite impulse response (IIR) notch filtering for estimating sinusoids imbedded in noise. Two notch filter model structures are presented. The first is for applications where one has access to two signal sources with correlated noise components. The second can be used in situations where only one composite signal source is available. Error surface analysis indicates that second-order modules are unimodal and result in guaranteed convergence. Higher order modules are multimodal and require judicious choice of initial parameter estimates. Simulation results are also included to demonstrate the performance characteristics of both filter structures. © 1990 IEEE
