An Improved Adaptive IVMD-WPT-Based Noise Reduction Algorithm on GPS Height Time Series

An Improved Adaptive IVMD-WPT-Based Noise Reduction Algorithm on GPS Height Time Series

To improve the reliability of Global Positioning System (GPS) signal extraction, the traditional variational mode decomposition (VMD) method cannot determine the number of intrinsic modal functions or the value of the penalty factor in the process of noise reduction, which leads to inadequate or ove...
