摘　　要：本文主要在乘性噪声之间相关、乘性和加性噪声之间也相关的复杂噪声背景下 ,研究谐波恢复及非线性耦合谐波分析 ,提出噪声互可混的概念 ,推广了有关非线性耦合谐波分析的结论 ,用特殊定义的六阶时间平均矩谱切片成功地解决了复杂噪声背景下的谐波恢复问题 .仿真实验证明了算法的有效性 .In this paper,the harmonic retrieval and frequency coupled harmonics are studied under the condition that the complex noise include multiplicative and additive noise are correlative.First,the concept of cross mixing is proposed.Second,the result on the frequency coupled harmonics are extended.Third,the harmonic retrieval in the complex noise is solved with the slice of the sixth order time averaged moment polyspectral.The above algorithms are confirmed by the simulations.
