The role played in the windowed Fourier transform by the family of functions $${\\\omega _{v,b}}(t) = \\\omega (t - b){e^{ + 2i\\\pi vt}},\\\quad b,v \\\in \\\mathbb{R}$$ is played in the wavelet transform (WT) by a family (16) $${\\\psi _{a,b}}(t) ...
In this paper, an analog implementation of the Wavelet Transform (WT) is presented. The circuit is based on the Dynamic Translinear (DTL) circuit technique and implements, by means of cascade connected complex first order systems, an analog filter whose impulse response is a Gabor function, a ...
This approach shows the experiment-based difference between the wavelet transform (WT) and the discrete wavelet packet transform (DWPT) to serve as a key role for finding electrochemical characteristics from a battery. Due to the unique feature of the multi-resolution analysis (MRA)-based decomposit...
THE WAVELET TUTORIAL PART 2 FUNDAMENTALS: THE FOURIER TRANSFORM AND THE SHORT TERM FOURIER TRANSFORM FUNDAMENTALS Let's have a short review of the first part. We basically need Wavelet Transform (WT) to analyze non-stationary signals, i.e., whose frequency response varies in time. I have ...
In this paper, we propose and analyze the wavelet transform-domain LMS (WTDLMS) algorithm where only a subset of the adaptive filter coefficients are updated at each iteration. The use of wavelets or subband filterbanks can lead to several novel schemes whose combinations can lead to other sub...

They kept track of the heart rate recordings and used the wavelet transform to evaluate the data (WT). Neuro-fuzzy evaluation approaches were used to improve the reliability of HRV analysis and to track the activity of the autonomic nervous system (ANS) under a variety of stress conditions. ...
Digital modulation identification by wavelet analysis There is a need to determine the modulation type of an incoming signal. This paper proposes the use of the wavelet transform (WT) for modulation identifica... J Chen,Y Kuo,J Li,... 被引量: 27发表: 2005年 Modulation Identification of Digi...
The energy distribution of a non-stationary signal is often represented by the squared magnitude of the wavelet transform (WT) or the short-time Fourier transform (STFT). The energy distribution contains cross terms, which can cause problems while analyzing the multicomponent signals. In this paper...
