HIGHER-ORDER WIGNER DISTRIBUTIONS
HIGHER-ORDER WIGNER DISTRIBUTIONS
收藏 引用
CONF ON advanced signal processing algorithms, architectures, AND implementations 3
作者: SWAMI, A Unocal Corp. (United States)
Higher-order Wigner distributions are not unique: definitions differ in the lag separations between the terms used in the time-domain product, as well as in how many of the terms are conjugated. We study a class of th... 详细信息

作者: HUNG, HS WHU, KR Iowa State Univ. (United States)
A direction-finding algorithm employing the technique of array manifold interpolation is proposed for the estimation of directions-of-arrival of multiple narrow-band sources. The algorithm is formulated by applying ar... 详细信息

作者: LUK, FT QIAO, SZ Rensselaer Polytechnic Institute (United States) McMaster Univ. (Canada)
The problem of linearly constrained least squares has many applications in signal processing. In this paper, we present a perturbation analysis of a novel, linearly constrained least squares algorithm for adaptive bea... 详细信息

作者: TAO, DL HAN, YS HARTMANN, CRP SUNY/Stony Brook (United States) Syracuse Univ. (United States)
The algorithm-based fault tolerance (ABFT) provides low-cost error protection for VLSI processor arrays used in real-time digital signal processing. Several ABFT techniques (weighted check-sum) have be proposed to des... 详细信息

作者: COHEN, L Rutgers Univ. (United States)
A simple formulation is given for generating convolution theorems in any representation. Using this method we obtain the convolution theorem for the scale representation. We generalize the concept of invariance to any... 详细信息

CONF ON advanced signal processing algorithms, architectures, AND implementations 3
作者: HUNG, HS MAO, CY Iowa State Univ. (United States)
A robust focusing matrix, called unitary constrained array manifold focusing, is proposed for the coherent signal-subspace method which is a novel approach for direction finding of broad- band sources. The proposed fo... 详细信息

CONF ON advanced signal processing algorithms, architectures, AND implementations 3
作者: CUNNINGHAM, GS WILLIAMS, WJ Univ. of Michigan (United States)
Cohen's class of time-frequency distributions has been recognized to have significant potential for the analysis of complicated signals. The spectrogram, though it offers comparatively lower time-frequency resolut... 详细信息

CONF ON advanced signal processing algorithms, architectures, AND implementations 3
作者: CHANG, TH KUO, CCJ Univ. of Southern California (United States)
A tree-structured wavelet transform has been developed for texture classification in our previous work. The new transform, which offers a non-redundant representation, is able to zoom into dominant frequency channels ... 详细信息

advanced signal processing algorithms, architectures, and implementations III
作者: Reilly, Andrew P. Boashash, Boualem Queensland Univ. of Technology Brisbane Queensland Australia
Techniques for machine recognition of speech exist, but use representations of the speech signal which cannot convey some of the speech information. Alternatives from time-frequency and time-scale analysis are compare... 详细信息
