In this paper, we apply the complexity?regularization principle to Poisson imaging. We formulate a natural distortion measure in image space, and present a connection between comp...

We propose a variant of Orthogonal Matching Pursuit (OMP), called LoCOMP, for scalable sparse signal approximation. The algorithm is designed for shift-invariant signal dictionari...

— Traditional multiple-antenna detectors – which search a tree or a lattice structure – typically apply a metric that requires a preprocessing. Contrary to that, we present a...

Abstract. We develop a refinement of a forbidden submatrix characterization of 0/1-matrices fulfilling the Consecutive Ones Property (C1P). This novel characterization finds app...

In digital signal processing, we often use higher radix system to achieve high-speed computation. In such cases, we require radix converters. This paper considers the design of LU...
