2-D frequency estimation, cross-mixing, time-average moment spectrum and cyclic statistics.
In this paper, the problem of frequency estimation of two-dimensional (2-D) harmonics in the presence of correlative multiplicative and additive noise are presented. We propose a 2-D cyclic statistic-based approach to this problem. A special 2-D slice of the six-order time-average moment spectrum is defined to estimate frequency in correlative zero mean multiplicative and additive noise. The effectiveness of our methods is demonstrated through some simulation examples.
