我们提出了一种新颖的自适应滤波方法，用于动态表征任意噪声背景中嵌入的不同频率和幅度的波。这种方法被称为 IWAVE（迭代波作用角变量估计器），与传统技术相比具有关键优势，使其成为动态表征包含嵌入振荡信号的各种数据的有用新工具。在回顾现有技术后，我们提出了 IWAVE 算法，得出其关键特征，并使用模拟和真实数据对其性能进行测试。
We present a novel adaptive filtering approach to the dynamic characterization of waves of varying frequencies and amplitudes embedded in arbitrary noise backgrounds. This method, known as IWAVE (Iterative Wave Action angle Variable Estimator), possesses critical advantages over conventional techniques, making it a useful new tool in the dynamic characterization of a wide range of data containing embedded oscillating signals. After a review of existing techniques, we present the IWAVE algorithm, derive its key characteristics, and provide tests of its performance using simulated and real world data.
