A Efficient Method For Estimating Parameters of Two-Dimensional Harmonics In Colored Gaussian Noise

摘要

In this paper, we address the problem of estimating parameters of multiple two-dimensional harmonics in colored Gaussian noise. The fourth-order moments of the available 2-D data, which is insensitive to colored gaussian noise but contains the information of frequencies and amplitudes of the 2-D harmonics, are used to construct two matrices. Then we decompose the original two-dimensional problem into two one-dimensional problems. A paring method is introduced to finish the 2-D estimation. Simulations are provided to show the efficiency of this method.
