Two-Dimensional Harmonics Parameters Estimation Using Third-Order Cyclic-Moments
Hongwei Li · Dianzi xuebao · 2005
The two-dimensional(2-D) harmonics parameters estimation in multiplicative and additive noise is studied from the viewpoint of cyclostationary processes.Using the property of cyclic cumulants,the statistical properties of the single record estimator of 2-D third-order cyclic-moments are obtained.A new method for 2-D harmonics parameters estimation based on special slice of the third-order cyclic-cumulants is presented.The strong compatibility and convergence rate of the estimators are obtained.Simulation examples illustrate the algorithm.
