摘要

分析了乘性噪声和加性噪声中的耦合谐波。我们提出了一种切片多光谱方法来识别三次耦合谐波。考虑了乘性噪声和加性噪声中二次耦合谐波频率的估计问题，提出了一种新的估计方法，消除了现有方法中对非零均值乘性噪声的假设。仿真示例说明了算法。

The analysis of coupled harmonics in multiplicative and additive noise

The coupled harmonics in multiplicative and additive noise is analyzed. We propose a slice polyspectra approach to identify cubic coupling harmonics. We also consider the problem of estimation of quadratic coupling harmonic frequencies in multiplicative and additive noise and propose a new method which obviates the assumption of multiplicative noise with nonzero mean in the existing method. Simulation examples illustrate the algorithms.
