A multiple birthday attack on NTRU

In this paper we view the possibilities to lance a multiple (iterative) birthday attack on NTRU. Recently Wagner's algorithm for the generalized birthday problem (Wagner, 2002) allowed to speed-up several combinatorial attacks. However, in the case of NTRU ...

Soft-output sphere decoding: Algorithms and VLSI implementation

Andreas Peter Burg, Christoph Studer

Multiple-input multiple-output (MIMO) detection algorithms providing soft information for a subsequent channel decoder pose significant implementation challenges due to their high computational complexity. In this paper, we show how sphere decoding can be ...

A Statistical Analysis of Certain Iterative Learning Control Algorithms

Alireza Karimi, Roland Longchamp, Mark Edward John Butcher

Iterative Learning Control (ILC) is a technique used to improve the tracking performance of systems carrying out repetitive tasks, which are affected by deterministic disturbances. The achievable performance is greatly degraded, however, when non-repeating ...

Steady-State Performance Analysis of a Variable Tap-Length LMS Algorithm

Ali H. Sayed, Ning Li

A steady-state performance analysis of the fractional tap-length (FT) variable tap-length least mean square (LMS) algorithm is presented in this correspondence. Based on the analysis, a mathematical formulation for the steady-state tap length is obtained. ...

Identification of PieceWise Affine Models of Genetic Regulatory Networks: the Data Classification Problem

Giancarlo Ferrari Trecate

In this paper we consider the identification of PieceWise Affine (PWA) models of Genetic Regulatory Networks (GRNs) and focus on data classification that is a task of the whole identification process. By assuming that gene expression profiles have been spl ...

Tracking Atoms with Particles for Audio-visual Source Localization

Pierre Vandergheynst, Andrea Cavallaro, Gianluca Monaci, Emilio Maggio

We present a general framework and an efficient algorithm for tracking relevant video structures. The structures to be tracked are implicitly defined by a Matching Pursuit procedure that extracts and ranks the most important image contours. Based on the ra ...
