Generator Coherency Using the Hilbert–Huang Transform

IEEE Transactions on Power Systems, 2008
Coherency between generators is tracked, by examining the instantaneous phase differences among interarea oscillations and swing curves in disturbed multiarea power systems. Huang's empirical mode decomposition is applied to extract dominant oscillatory modes from interarea oscillations/swing curves.

Hilbert-Huang Transform and Wavelet Transform for ECG Detection

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008
HHT (Hilbert transform) and wavelet transform are both signal processing methods. This paper is based on HHT and wavelet transform to detect R peak. Firstly using wavelet transform to de-noise, then we are focus on using the empirical mode decomposition (EMD) to electrocardiogram (ECG) which can be decomposed into a limited number of IMF (intrinsic ...

Hilbert-Huang Transformation based solar light noise suppression method

2015 4th International Conference on Computer Science and Network Technology (ICCSNT), 2015
Solar light noise, as the main part of channel noise in outdoor visible light communication (VLC) system, would easily saturate the photon-detector, and dramatically decrease the outdoor VLC system performance. A Hilbert-Huang Transformation based solar light noise suppression method is proposed in this paper, a background light noise measurement ...

Hilbert-Huang Transform Associated with the Linear Canonical Transform

2011 First International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2011
In recent years, the Hilbert - Huang transform and the linear canonical transform draw extensive attention in signal processing community, especially in Radar, optical signal processing and so on. This paper investigates the Hilbert - Huang transform associated with the linear canonical transform and the algorithm for the non-stationary signal ...

Electromagnetic Shielding Analysis Using Hilbert-Huang Transform

In this study, the Hilbert-Huang Transform (HHT) and other frequency analysis methods, Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT), are employed to numerically analyze electromagnetic phenomena with strong non-linearity. In the numerical experiments, electromagnetic wave propagation simulations using the Finite-Difference

Speech pitch determination based on Hilbert-Huang transform

Signal Processing, 2006
Pitch determination is an essential part of speech recognition and speech processing. In this paper, a new pitch determination method based on Hilbert-Huang Transform (HHT) is presented. The assumption of linearity of the speech-production process and short-time stationarity of speech signals, which is generally employed in recent studies on speech ...

Defining an estuary using the Hilbert-Huang transform

Hydrological Sciences Journal, 2013
Abstract Researchers have used various physical, chemical, or topographic features to define estuaries, based on the needs of their particular subject. The principal features of estuaries are the tides that influence their water stages; thus, the boundaries of an estuary can be determined based on whether the water stage is subject to tidal influence ...

Short-termflickerseverity indexcalculation using Hilbert-Huang Transform

2011
This article proposes an approach to calculate the short term flicker magnitude (Pst) using Hilbert-Huang Transform (HHT). HHT is an approach which is commonly used in the analysis of nonlinear and nonstationary signals. Since flicker corresponds to a variation of the envelope of a sinusoidal voltage waveform, the utilization of HHT is reasonable.
