摘要

提出了一种特殊的四阶时间平均矩谱方法来估计三次非线性耦合。利用该方法可以得到任意平均乘性噪声和加性噪声相互独立，乘性噪声相互关联的噪声中的耦合频率和耦合频率。同时，该方法不需要对图像的分布和颜色噪声进行约束。仿真示例说明了算法。

Cubic nonlinear coupling estimation in correlative multiplicative noise

A special four-order time-average moment spectrum approach is proposed for estimating cubic nonlinear coupling. It can be applied to obtain the coupled and coupling frequencies in the noise that any mean multiplicative and additive noises are mutually independent, the multiplicative noises are correlative. In the meantime, this method needn't constrain the distribution and the color noises. Simulation examples illustrate the algorithms.
