摘要

本文提出了一种基于循环统计量的三次非线性耦合谐波过程二维频率估计算法。我们定义了一个四阶时间平均矩谱。该方法可用于求解非零均值乘性噪声下的耦合频率和耦合频率。该方法不需要约束噪声的分布和颜色。仿真示例说明了算法。

Two-dimensional cubic nonlinear coupling estimation in nonzero-mean multiplicative noise

This paper describes an algorithm based on cyclic statistic to estimate the two-dimensional (2-D) frequency of harmonic process which cubic nonlinear coupling exists. We defined a fourth-order time-average moment spectrum. It can be applied to obtain the coupled and coupling frequencies in nonzero-mean multiplicative noise. This method needn't constrain the distribution and the color of noises. Simulation examples illustrate the algorithms.
