A Compressed Sensing Parameter Extraction Platform for Radar Pulse Signal Acquisition
Compressed sensing Indium-Phosphide Parameter Estimation Random-Modulation Pre-Integration
2015/6/17
In this paper we present a complete (hardware/software) sub-Nyquist rate (×13) wideband signal acquisition chain capable of acquiring radar pulse parameters in an instantaneous bandwidth spanning 100 ...
Image Authentication Using Added Signal-Dependent Noise
Image Authentication Added Signal-Dependent Noise
2009/9/4
Image authentication has applications in security systems, photo forensics, and photo journalism. This paper presents an image authentication scheme using added signal-dependent noise. Imperceptible n...
Open Quotient Measurements Based on Multiscale Product of Speech Signal Wavelet Transform
Open Quotient Measurements Multiscale Product Speech Signal Wavelet Transform
2009/9/4
This paper describes a multiscale product method (MPM) for open quotient measure in voiced speech. The method is based on determining the glottal closing and opening instants. The proposed approach co...
AN ALGORITHM FOR THRESHOLDING IN THE CONTEXT OF SIGNAL DENOISING WITH WAVELETS
signal processing analysis denoising filtering
2010/1/11
The problem of estimating a signal corrupted by additive noise has been of
interest to many researchers for practical as well as theoretical reasons. Wavelet based
methods have become increasingly p...
ON THE HARMONICS REDUCTION USING WAVELET BASED SIGNAL PROCESSING
harmonic reduction wavelet analysis active filter
2010/1/13
This paper presents a method for calculating the reference currents needed for
the command of an active filter. By using the Discrete Wavelet Transform (DWT) the
high-frequency components of the cur...
