IEEE Workshop on Signal Processing Advances in Wireless Communications (SPAWC)
作者: Sergio Barbarossa Gesualdo Scutari Timothy Battisti INFOCOM Department University of Roma La Sapienza Rome Italy
Sensing the radio spectrum is an essential feature of cognitive radio. What is mostly important for a cognitive transmitter is to know the power spectral density at the location of its intended receiver and of the pri... 详细信息

European Signal Processing Conference (EUSIPCO)
作者: Wail A. Mousa Said Boussakta Des McLernon School of Electronic & Electrical Engineering The University of Leeds Leeds United Kingdom
The iterative Pure and Relaxed Projectors are special cases of Vector Space projection Methods (VSPM). Complex-valued FIR digital filter design using Pure and Relaxed Projectors is proposed for designing seismic migra... 详细信息

International Symposium on Signals, Circuits and Systems (ISSCS)
作者: F. Albu C. Kotropoulos Z. Cernekova I. Pitas Department of informatics Aristotle University of Thessaloniki Thessaloniki Greece
This paper proposes a robust and stable fast affine projection algorithm based on the Gauss-Seidel method, the so called modified Gauss-Seidel fast affine projection algorithm. The proposed algorithm is generalized fo... 详细信息

American Control Conference (ACC)
作者: E. Beran K.M. Grigoriadis Department of Automation and Department of Mathematics Technical University of Denmark Lyngby Denmark Department of Mechanical Engineering University of Houston Houston TX USA
Alternating projection algorithms have been introduced recently to solve fixed-order controller design problems described by linear matrix inequalities and non-convex coupling rank constraints. In this work, an extens... 详细信息

European Signal Processing Conference (EUSIPCO)
作者: Miguel Ferrer Alberto Gonzalez Maria de Diego Gema Piñero Universitat Politecnica de Valencia Valencia Valenciana ES Institute of Telecommunications and Multimedia Applications (iTEAM) Universidad Politecnica de Valencia
In the field of adaptive filtering, it is well known that affine projection (AP) algorithms lead to a good tradeoff between convergence speed and computational load. For multichannel sound control, some computationall... 详细信息

Midwest Symposium on Circuits and Systems (MWSCAS)
作者: Tao Dai B. Shahrrava Department of Electrical and Computer Engineering University of Windsor Windsor ONT Canada
In this paper, we propose two new variable step-size normalized least mean square (NLMS) and affine projection algorithms (APA) with variable smoothing factor. Simulation results illustrate that the proposed algorithm... 详细信息

IEEE Annual Conference on Decision and Control
作者: Angelia Nedic Ion Necoara Electrical Computer and Energy Engineering Department Arizona State University Tempe AZ USA Automatic Control and Systems Engineering Department University Politehnica Bucharest Bucharest Romania
This paper deals with the convex feasibility problem where the feasible set is given as the intersection of a (possibly infinite) number of closed convex sets. We assume that each set is specified algebraically as a c... 详细信息

作者: A. Carini G.L. Sicuranza STI University of Urbino Urbino Italy DEEI University of Trieste Trieste Italy
The paper provides an analysis of the steady-state and transient behavior of two filtered-x affine projection algorithms suitable for multichannel active noise control. The analysis relies on energy conservation argum... 详细信息

IEEE International Conference on Image Processing
作者: P.L. Combettes Laboratoire d'Analyse Numerique Université Pierre et Marie Curie Paris France
In image recovery, convex projection methods have been in use for almost two decades. However, while it is well known that projections can seldom be computed exactly, the effect of inexact projections on the behavior ... 详细信息

IEEE International Symposium on Circuits and Systems (ISCAS)
作者: S.G. Sankaran A.A. Beex The Bradley Department of Electrical and Computer Engineering Systems Group-DSP Research Laboratory Blacksburg VA USA
Over the last decade, a class of equivalent algorithms called the affine projection class of algorithms, which accelerate the convergence of the normalized LMS (NLMS) algorithm, has been discovered independently. The ... 详细信息
