Denoising GPS-Based Structure Monitoring Data Using Hybrid EMD and Wavelet Packet
High-frequency components are often discarded for data denoising when applying pure wavelet multiscale or empirical mode decomposition (EMD) based approaches. Instead, they may raise the problem of energy leakage in vibration signals. Hybrid EMD and wavelet packet (EMD-WP) is proposed to denoise Glo...
