On homomorphic deconvolution of bandpass signals
收藏 引用
IEEE TRANSACTIONS ON signal processing 1997年 第10期45卷 2499-2514页
作者: Marenco, AL Madisetti, VK Center for Signal and Image Processing (CSIP) Georgia Institute of Technology School of Electrical and Computer Engineering Atlanta GA USA
A convolution may be represented as x(.) = r(.)* w(.). The goal of deconvolution is to extract r(.) and w(.) from a knowledge of x(.) and finds numerous applications in digital signal processing, Of practical interest... 详细信息

Spatio-temporal wavelet transforms for digital signal analysis
收藏 引用
signal processing 1997年 第1期60卷 23-41页
作者: Leduc, JP Georgia Institute of Technology School of Electrical and Computer Engineering Center of Signal and Image Processing Atlanta GA 30332-0250 USA
The goal of this paper is to investigate spatio-temporal continuous wavelet transforms. A new wavelet family, called the Galilean wavelet, has been designed to tune to four main parameters, namely, scale, spatio-tempo... 详细信息

Sinusoidal modeling and modification of unvoiced speech
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO processing 1997年 第6期5卷 557-560页
作者: Macon, MW Clements, MA Oregon Graduate Institute of Science and Technology Portland OR USA Center for Signal and Image Processing The Georgia Institute of Technology School of Electrical and Computer Engineering Atlanta GA USA
Although sinusoidal models have been shown to be useful for time-scale and pitch modification of voiced speech, objectionable artifacts often arise when such models are applied to unvoiced speech. This correspondence ... 详细信息

A secure communications system using chaotic switching
收藏 引用
INTERNATIONAL JOURNAL OF BIFURCATION AND CHAOS 1997年 第6期7卷 1383-1394页
作者: Lee, C Williams, DB Lee, J Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA 30332-0250 USA
Since previous secure communications methods using chaotic systems require very high SNRs, knowledge of the initial conditions, and/or chaotic systems with the self-synchronization property, their application is limit...
