Conference on advanced signal processing algorithms, architectures, and implementations IX
作者: Nelson, D Cristóbal, G Kober, V Cakrak, F Loughlin, P Cohen, L US Dept Def Ft Meade MD 20755 USA
We present a number of methods that use image and signed processing techniques for removal of noise from a signal. The basic idea is to first construct a time-frequency density of the noisy signal. The time-frequency ... 详细信息

Conference on advanced signal processing algorithms, architectures, and implementations IX
作者: Lo Presti, L Olmo, G Galleani, L Politecn Torino Dipartimento Elettron I-10129 Turin Italy
In this paper, a method for signal component separation, operating in the Time-Frequency (TF) plane and employing a Turbo Estimation Algorithm (TEA), is described. A novel 2D distribution is proposed, named Two Window... 详细信息

Conference on advanced signal processing algorithms, architectures, and implementations IX
作者: Izzetoglu, M Akgül, T Drexel Univ Dept Elect & Comp Engn Philadelphia PA 19104 USA
In this paper we introduce a. multi-scale deconvolution technique performed in the scale-domain. In sensor array applications such as in radar, sonar and seismic processing, the sensor outputs are modeled as the convo... 详细信息

Conference on advanced signal processing algorithms, architectures, and implementations IX
作者: McWhirter, JG Clarke, IJ Spence, G Def Evaluat & Res Agcy Malvern WR14 3PS Worcs England
It is shown how some simple multilinear transformations may be used to generate an alternative, and potentially faster, version of the BLISS algorithm for blind signal separation. The BLISS algorithm performs an indep... 详细信息

Conference on advanced signal processing algorithms, architectures, and implementations IX
作者: Nair, D Wenzel, L Natl Instruments Austin TX 78727 USA
It is well known that high-dimensional integrals can be solved with Monte Carlo algorithms. Recently, it was discovered that there is a relationship between low discrepancy sets and the efficient evaluation of higher-... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Martinez, J.J. Pena, J.M. Universidad de Alcala Madrid Spain
Cauchy-Vandermonde matrices are related with rational interpolation problems. In this paper we consider the general case in which multiple poles can appear. Fast algorithms for solving the corresponding linear systems... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Suter, Bruce W. Lindsey, Alan R. Air Force Research Lab Rome United States
Investigating a number of different integral transforms uncovers distinct patterns in the type of scale-based convolution theorems afforded by each. It is shown that scaling convolutions behave in quite a similar fash... 详细信息
