Application of Hilbert-Huang transform in the analysis of satellite-communication signals

open access: yesRevista Iberoamericana de Automática e Informática Industrial RIAI, 2020
In communication links between satellites and ground stations, the transmitted signal is exposed to disturbances such as noise of different types that hinder reception or retrieval of information.

A Comparative Study of Time-Frequency Representations for Fault Detection in Wind Turbine [PDF]

open access: yes, 2011
To reduce the cost of wind energy, minimization and prediction of maintenance operations in wind turbine is of key importance. In variable speed turbine generator, advanced signal processing tools are required to detect and diagnose the generator faults ...

IRIS RECOGNITION BASED ON HILBERT–HUANG TRANSFORM

open access: yesAdvances in Adaptive Data Analysis, 2009
As a reliable approach for human identification, iris recognition has received increasing attention in recent years. This paper proposes a new analysis method for iris recognition based on Hilbert–Huang transform (HHT). We first divide a normalized iris image into several subregions.

THE APPLICATION OF HILBERT–HUANG TRANSFORMS TO METEOROLOGICAL DATASETS [PDF]

open access: yesJournal of Atmospheric and Oceanic Technology, 2004
Recently a new spectral technique as been developed for the analysis of aperiodic and nonlinear signals - the Hilbert-Huang transform. This paper shows how these transforms can be used to discover synoptic and climatic features: For sea level data, the transforms capture the oceanic tides as well as large, aperiodic river outflows. In the case of solar

Application of the Hilbert-Huang transform to the search for gravitational waves [PDF]

open access: yesPhysical Review D, 2007
We present the application of a novel method of time-series analysis, the Hilbert-Huang Transform, to the search for gravitational waves. This algorithm is adaptive and does not impose a basis set on the data, and thus the time-frequency decomposition it provides is not limited by time-frequency uncertainty spreading. Because of its high time-frequency

Drilling-vibration response characteristics of rocks based on Hilbert–Huang transform

open access: yesJournal of Petroleum Exploration and Production Technology, 2023
Currently, there are no in-situ methods to quantify drilling-vibration response characteristics of different lithologies. Here, we quantified the vibration responses of four lithologies (limestone, sandstone, coal, and mudstone) using a combination of ...

Gear Fault Detection Based on Teager-Huang Transform

open access: yesInternational Journal of Rotating Machinery, 2010
Gear fault detection based on Empirical Mode Decomposition (EMD) and Teager Kaiser Energy Operator (TKEO) technique is presented. This novel method is named as Teager-Huang transform (THT).
