Modulation classification by Hilbert-Huang Transform

open access: yes2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
The problem of identifying the modulation type of the signals at the receiver, is very helpful intermediate step for spectrum sensing which the cognitive radio systems are commonly used today. In this study, Hilbert-Huang Transform is proposed for identifying the modulation type of digitally modulated signals in the noisy environments.

Mode Decomposition and the Hilbert-Huang Transform

open access: yes2019 Russian Open Conference on Radio Wave Propagation (RWP), 2019
The paper presents a relatively new method for the analysis of nonstationary and nonlinear processes called Hilbert-Huang transform. The Hilbert-Huang transform consists of two stages: Empirical mode decomposition and Hilbert Spectral Analysis. The empirical mode decomposition is a signal analysis method that separates multi-component signals into ...

Segmentation of Killer Whale Vocalizations Using the Hilbert-Huang Transform [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
The study of cetacean vocalizations is usually based on spectrogram analysis. The feature extraction is obtained from 2D methods like the edge detection algorithm.

Wheeze detection in the respiratory sounds using Hilbert-Huang transform

open access: yes2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
Wheezes in the respiratory sounds are indicators for a number of diseases. Automatic detection of these signals — which have musical character and one or more dominant frequencies-is very important. In this study investigation of wheeze detection in the respiratory sounds using Hilbert-Huang transform is studied.

Data Mining Applied to the Electrochemical Noise Technique in the Time/Frequency Domain for Stress Corrosion Cracking Recognition

open access: yesCorrosion and Materials Degradation, 2023
In this paper, time/frequency domain data processing was proposed to analyse the EN signal recorded during stress corrosion cracking on precipitation-hardening martensitic stainless steel in a chloride environment.
