Fully Adaptive Time-Varying Wave-Shape Model: Applications in Biomedical Signal Processing
Joaquin Ruiz, Gastón Schlotthauer, Leandro Vignolo +1
In this work, we propose a time-varying wave-shape extraction algorithm based on a modified version of the adaptive non-harmonic model for non-stationary signals. The model codifie…

Wave-shape Function Model Order Estimation by Trigonometric Regression
Joaquin Ruiz, Marcelo A. Colominas
The adaptive non-harmonic (ANH) model is a powerful tool to compactly represent oscillating signals with time-varying amplitude and phase, and non-sinusoidal oscillating morphology…

Enhancing Missing Data Imputation of Non-stationary Signals with Harmonic Decomposition
Joaquin Ruiz, Hau-tieng Wu, Marcelo A. Colominas
Dealing with time series with missing values, including those afflicted by low quality or over-saturation, presents a significant signal processing challenge. The task of recoverin…
